Research Finds That Rats Have Imagination

Published: November 27th, 2023

Do animals have imagination? Many people wonder if animals are capable of imagining things in their minds the same way that humans can. Could a rat, for example, use their imagination? Recent research has shown that, yes, they can, at least to a similar degree as people.

Diving into the Way a Rat’s Mind Works

If you’re sitting at home or in your office, and you decide to think about your friend’s house, your favorite vacation spot, or anything in between, you can easily see it in your mind, and you can imagine yourself moving through it. But experts wondered if animals can do the same.

A study from the Howard Hughes Medical Institute Janelia Research Campus uncovered that rats are capable of seeing places in their mind (places that they aren’t physically in). In other words, they can think of distant places whenever they want. This is a type of imagination that makes it possible for the animals to think of themselves in a place that they were in in the past, and also gives them the ability to envision themselves in that place in the future.

A Brain-Machine Interface Showing How Rats Think

How did experts figure this out? They surgically implanted electrodes in the brains of rats. Then, they put the rats on a treadmill ball inside a virtual reality environment. On a screen, there was a goal that the rats were to move towards and, as they moved, their place in the virtual space changed on the screen to make it appear real. The rats were given a treat once the goal was reached. And, as the rats moved through the experiment, the researchers recorded the activity of the hippocampus in the brain.

Next, the rats were put back in the virtual environment, but they weren’t put on the treadmill, so they had to use brain activity to navigate the space. Once again, the experts looked at the hippocampus as the rats went through the experiment and reached their goals. And, in yet another test, the rats remained stationary while directing an object in the virtual environment to a particular goal using their mind.

All of this is to say that experts determined that rats can imagine. Also, this research sheds light on the fact that rats are pretty amazing, which is why they make great pets, and it further proves that we still have a lot to learn about them and other animals.

Study Finds Differences in Pain Sensitivity Between Dog Breeds

Although you might think that all dogs experience pain the same, it turns out that different dog breeds have varying levels of pain sensitivity.

Sleeping With Pets: Here's What Experts Have to Say

Pet parents adore their four-legged companions so much that they choose to sleep with them at night. Research shows that more than half of pet owners sleep with their pets. Most pet owners consider their pets part of the family, so it is no surprise that they will go out of their way to ensure their furry companions’ comfort. However, with an increasing focus on our sleep health, pet parents are starting to wonder about the potential disadvantages of sleeping with pets. In fact, sharing a bed with a pet is the subject of controversy among pet parents.Various studies suggest that there are many benefits to sleeping with pets. And experts tend to agree. According to Audrey Wells, MD, a board-certified sleep medicine physician, a pet can provide an emotional connection and reduce anxiety and stress levels, therefore promoting sleep. “Some people may consider their pets an added layer of security, dependable to alert them to unexpected noises or lights.”Another benefit of sleeping with your pet is that they can keep you nice and warm during the night. People who get chilled easily might enjoy cuddling with a furry companion during frigid winter nights.“Pets are sensitive to routine, and they can help enforce a regular bedtime and better sleep quality for their owner,” explained Dr. Wells. “Similarly, pets can signal wake-up time in the morning and even prompt some time outside for a walk and daylight exposure.”If you enjoy sleeping with your pet and find it beneficial for your sleep, the science agrees with you. According to Amanda Farah, National Training and Behavioral Coordinator at Best Friends Animal Society, studies have found that some people sleep more soundly when their dog is sleeping next to them. “If you and your dog both sleep well together, you’ll enjoy the health benefits that come with a good night’s sleep, such as improved mental clarity, lower blood pressure, reduced stress, and a stronger immune system,” explained Farah.According to Teddy Cralle, Ms, RN, certified clinical sleep educator, some people sleep better when their pet is in the bed, but some don’t. If there’s a chance that you won't get a good night’s rest while sleeping with your pet you shouldn't sleep with them in the first place. For example, if you’re a light sleeper and your dog likes to change positions during the night, sleeping with your pooch may wake you more often, resulting in low-quality sleep. Also, some pups like to claim the entire bed for themselves, leading to a sleepless night and a backache. “Sacrificing your sleep means sacrificing your health, well-being, and quality of life - and that is not a sacrifice to make,” Cralle added.Sharing a bed with a pet may not be the best idea if you’re an asthma or allergy sufferer. Although some dog breeds shed less than others, no dog is truly hypoallergenic because it’s their dander and not hair that triggers an allergic reaction. Zoonotic diseases are another downside of sleeping with pets. Research has confirmed that sharing a bed with a pet can increase the exposure rate to pathogens that might be present. Although no one wants to think about it, pets can bring unwanted guests to your bed. Fleas and ticks are the most active during the warmer months, but the truth is they can infest your pet all year long. If the downsides of sleeping with your pet have made you reconsider your sleeping arrangement don’t fret - you can still have your pooch close by while you sleep. A crate or a cozy dog bed next to your bed will help everyone get a good night’s rest. Join the PetGuide community.

Mind-Reading Pet Psychics Are a Burgeoning Business

Pet parents pay big bucks to communicate better with their best buddies.

What Age Should You Start Clicker Training?

Clicker training is a popular form of positive reinforcement dog training that uses a small handheld device called a clicker to mark and reinforce desired behaviors. The clicker makes a distinct and consistent sound that signals to the dog that they have performed the desired behavior, followed by a reward such as a treat or praise. The idea is to associate the sound of the clicker with the reward, making it a powerful tool for communication between the owner and the dog.Now, if you want to try clicker training with your dog, you could be wondering at what age should you start. Very early on? Or as your puppy grows a bit older? Let’s find out.What Age Should You Start Clicker Training?Clicker training is versatile and can be used for teaching  basic commands, tricks, and even addressing behavioral issues. It is a humane and positive approach to training that fosters a strong bond between the owner and the dog. Clicker training can be started with dogs at a relatively young age, typically when they are around 8 weeks old. Puppies are capable of learning basic commands and behaviors from a young age, and clicker training can be a positive and effective method for teaching them.However, it's important to keep in mind that very young puppies have shorter attention spans, so training sessions should be kept short and fun. Focus on simple commands and behaviors, and use positive reinforcement, such as treats or praise, in conjunction with the clicker.Consistency and patience are key when training puppies, and it's important to make the training sessions enjoyable for them. Stay consistent and maintain your composure and command. Even if the early training sessions last just a few minutes, keep it up. Of course, if you're unsure about how to start clicker training or have concerns about your puppy's readiness, consulting with a professional dog trainer or attending puppy training classes can be helpful. Always use positive reinforcement methods to create a positive and trusting relationship between you and your dog.Remember that clicker training requires patience and hard work to be successful. The idea is to associate the sound of the clicker with positive reinforcement, making it a powerful tool for communication between the owner and the dog.4 Things to Know About Clicker TrainingTo ensure your training sessions with a clicker are successful no matter when you start implementing them in your pet’s routine, you need to know the basics. These tips will help you optimize your process for maximum efficiency:Timing is KeyClicker training relies on precise timing. The click should occur at the exact moment your dog exhibits the desired behavior. This helps your dog make the connection between the behavior and the reward.Positive Reinforcement

Study Finds Pets Didn't Make People Happier During the Pandemic

Would you say that your pet help you feel better during the pandemic? Countless pet parents, myself included, would say they experienced less stress and anxiety during lockdown thanks to their four-legged companions. However, a new study led by researchers from Michigan State University suggests otherwise. Researchers couldn’t find a reliable association between pet ownership and well-being during the COVID-19 pandemic, even though owners claimed pets improved their lives. The pandemic was extremely stressful for everyone. The research team from Michigan State University theorized that the pandemic created ideal conditions to determine how much happiness and comfort pets actually provide to their families. The study, published in the Personality and Social Psychology Bulletin, evaluated 767 people on three separate occasions in May 2020. The researchers used a mixed-method approach, looking at several indicators of well-being. They also asked owners in an open-ended question to think about the role of pets. Unsurprisingly, pet owners reported their pets made them happy. Owners claimed pets help them feel more positive emotions and provide companionship and affection, but also expressed worry about their pet’s well-being and reported their pets interfered with working remotely. But when researchers compared the happiness of pet owners to levels seen in non-pet owners they made a surprising discovery. Shockingly, the data showed no difference in the well-being of pet owners and non-pet owners over time. The research team explained that it did not matter what type of pet people owned, how many pets they had, or how close owners were with their pets. The personalities of the owners weren’t a factor either. “People say pets make them happy, but when we actually measure happiness that doesn’t appear to be the case,” said William Chopik, an associate professor in MSU’s Department of Psychology and co-author of the study, in a university release. “People see friends as lonely or wanting companionship, and they recommend getting a pet. But it’s unlikely to be as transformative as people think,” added Chopik. The research team also explored several other potential reasons as to why there was no difference in the happiness levels of pet owners and non-pet owners. The most likely reason might be that non-pet owners have found ways to fill their lives with activities and interests that make them as happy as owning a pet would. “Staking all of your hope on a pet making you feel better is probably unfair and maybe costly, given other things you could do in your life that could improve your happiness,”  said Chopik. Another study, involving 4,237 people, beginning at the start of the pandemic and ending in December 2021, had similar findings. Although owners grew closer to their pets, especially dogs, during the pandemic, that didn’t stave off stress.In fact, the lowest stress levels were seen in non-pet owners. When you think about it, these results kind of make sense - pet owners had an additional mouth to feed during the lockdown and had limited opportunities to take their dogs out for a walk or play session. The results of these studies are surprising, to say the least. I was positive that I was happier than my poochless friends during the lockdown, but guess that wasn’t the case. After thinking about this a bit more, I realized that maybe we shouldn’t expect so much from our four-legged companions. Yes, there are many benefits to owning a pet, and pets can make us happy, but ultimately happiness depends on ourselves. Join the PetGuide community.

Unexpected Things That Helped Me Cope With Loss of My 17-Year-Old Cat

Getting to share your life with a pet is truly a privilege, as there’s not much that can rival the sheer joy and genuine love these little creatures bring to us. But when the time comes to say goodbye, the weight of grief can feel overwhelming. In these moments, it feels like nothing can help lighten the load we carry, but it’s crucial to remember that the journey through pet loss is a shared experience among countless others who have navigated the same emotional terrain.I recently found myself grappling with the profound loss of my beloved four-legged companion, a 17-year-old cat called Luna. Luna was not just a pet; she was a loyal friend for more than half of my life, a source of comfort during challenging times, and a bundle of joy who brightened even the gloomiest days. When Luna passed away, a void opened up in my heart, leaving me adrift in a sea of grief.

These Dog Foods Are Recalled Due to Potential Salmonella Contamination

Owners should always be careful about the food that they give to their pet – and it’s only natural that every caring owner will naturally want the best for their pet. But sometimes, even getting the best of the best is not a guarantee as accidents can happen anytime. In this case, the issue is that several popular dog food brands got potentially contaminated with salmonellla. Recently, owners had been shocked to find out that three brands of pet food were recalled - having tested positive for salmonella. And in fact, the past year saw at least seven recalls of dog food brands that were either contaminated with this nasty bacteria, or had harmful elevated levels of vitamins. And, to make matters worse, 2019 saw several dogs get seriously ill after consuming the food. And our dear four-legged friends are not the only ones at risk - handling the contaminated dog food, we too are exposed to salmonella. In 2012, up to 49 people in the United States and Canada fell ill after an outbreak of salmonella that was traced to dry dog food. According to the U.S. Centers for Disease Control and Prevention, 10 persons were so ill that hospitalization was required.According to the CDC, the pesky salmonella bacteria causes “an estimated 1.3 million infections in Americans every year, resulting in 26,500 hospitalizations and 420 deaths.”As for the latest recalls, a notice from the U.S. Food and Drug Administration, released on October 30th, includes the following foods: “one by Mid America Pet Food of Mount Pleasant, Texas, involving three lots of Victor Super Premium Dog Food, Select Beef Meal & Brown Rice Formula after random sampling found salmonella, which can sicken pets as well as people who come in contact with it.” Furthermore, it is stated that the food was “Sold by retailers across the U.S., the recalled products come in five-pound, 15-pound and 40-pound bags with a best-by-date of June 12, 2024, and contain one of the following three lot numbers on the back of the products: 1000016890, 1000016891, 1000016892.”The second recall involves TFP Nutrition of Nacogdoches, and their Retriever All Life Stages Mini Chunk Chicken Recipe Dry Dog Food, in 50lbs bags, with best-by-dates of October 2024 and production codes of either 3277 TFP or 3278 TFP. Lastly, the third recall in the latest wave is Blue Ridge Beef of Statesville, North Carolina, which is recalling Breeders Choice dog food with the UPC code 8 54298 00193 1 due to possible salmonella contamination.In case you suspect your pet has eaten any potentially infected foods, it is important to know the  symptoms of salmonella poisoning in pets: they can be lethargic, listless, or have diarrhea that is followed by fever and vomiting. If you recognise these in your pet, don’t hesitate to contact your vet. And, if you suspect that the dog food you have is contaminated, make sure to destroy it in a way that children, animals, or people cannot get in contact with it.

Halifax's Dalhousie University finds dogs can identify the adrenaline hormone through an individual's breath.

Lost Dog Rescued After Surviving Six Years Alone in the Woods

A senior dog found living in the woods in the U.K. has been rescued and is now looking for a loving home.The dog, named Rose, was first spotted near Crawley Down in West Sussex, England. The Lost Dog Recovery UK South shared in a social media post that they’ve received a message from a concerned member of the public about a small black dog running in the road.The person who saw the dog “stopped the traffic” and let the pooch disappear into the woods, knowing it’s best not to follow. After visiting the nearest property, the person learned that locals were familiar with the dog and that drivers often stopped by saying that the pooch had been on the road. The locals explained that the dog was a stray fed by people.The individual who spotted the dog was troubled by the idea of a dog living in the woods and contacted the Lost Dog Recovery rescue organization with this information. Knowing that this could be a case of an “owned dog allowed to roam” the organization decided to investigate by setting out food for the pooch along with cameras to track its movements. The dog was caught on camera five times in two days and by the third day appeared to be waiting for meals.The organization also talked with residents in the area about the dog and were told that the dog was a stray who lived locally for about ten years. The residents also said that the dog should be left alone because was in good condition, fed, and cared for. After talking about this situation with another household, which has been leaving food for wildlife and were allegedly responsible for the dog’s care, the rescue decided to help the dog. Over the following week, the organization established a feeding schedule and confirmed that the pooch was indeed a senior dog. They set a trap for the dog by serving a warm roast chicken and managed to catch her.“Understandably she was shocked and scared, but very gentle, and was taken immediately to the warmth and safety of kennels,” the organization shared.  After taking her to the kennels, the organization made a shocking discovery - the dog was microchipped! Her name was Rose and she had gone missing from her owners less than 24 hours after they adopted her in 2017! A now 12-year-old Patterdale terrier, Rose, has gone missing from Ashurst Woods, located only six miles away from Crawley Down, where the organization found her. Unfortunately, there was no happy reunion for Rose. The organization managed to contact Rose’s registered owners, but they explained that they were in no position to take her back since their circumstances had changed dramatically and they had moved away. “After the initial shock, our absolute joy at finding a long-lost dog is tinged with sadness as there is no happy reunion for Rose; she never got the chance to know the love of her family,” the organization said in a post. They added that Rose is going to need time, patience, and rehabilitation, and being a senior dog she’ll likely need ongoing vet care and medication. Rose is going to be cared for by Last Chance Animal Rescue in Edenbridge, U.K. After sharing Rose’s story, the rescue received several inquiries about her from families willing to adopt her and give her a safe, warm, and loving home.“Please don’t leave a dog straying for longer than they have to be...not only for them and their wellbeing but also for the sake of humans who love them,” the organization added. Join the PetGuide community.

How Do I Manage My Dog's Separation Anxiety When I'm At Work?

No one likes to be separated from their cherished pet for too long. But going to work is unavoidable for most of us, and, inevitably, our pets have to stay home alone. It might not seem like a big deal to you, knowing you’ll be back after a few hours, but it is definitely a big deal for your dog. In fact, most pet dogs are affected by this separation so much that they can experience anxiety and stress, ranging from mild discomfort to severe panic. Needless to say, this is traumatic for your pet (and can result in destroyed valuables, too) so it’s important to learn how to help them manage anxiety when you’re away. Here are some tips to help you navigate your pet’s separation anxiety while you’re at the office. 6 Ways To Prevent Dog Separation Anxiety When You’re At WorkGoing off to work and leaving their pet behind is a challenge for many pet owners around the world, especially those who live alone. When you're at the office, you need to make sure your pet is safe and taken care of until you come back. But even when you organize everything, your pet might feel stressed out on their own - even when it’s for a few hours, your dog won’t know why you left or even if you are coming back which can be a trigger for a panic attack for some canines. Some, especially  velcro dogs, get so nervous and stressed that they develop a separation anxiety disorder. But even so, there are many ways to help your pet cope when you're at work, regardless of the severity of their anxiety – here are 6 ways to reduce stress for your four-legged bestie.Create a Consistent Routine:Dogs thrive when they have a routine. Establish a consistent daily schedule for feeding, walks, and playtime. This helps them know what to expect and when. You can create their schedule around your work hours, so your pet will not find it odd that you are not there when they know what to expect before and after your shift (e.g. walk and mealtime).Gradual Departures and Arrivals:Don't make a big fuss when leaving or returning home. Keep your arrivals and departures low-key to reduce anxiety. This helps normalize the process. Make it seem like you just popped out for a few minutes. If you help your dog understand it is not a big deal, they might pick up on your relaxed energy and stay calm when you depart.Offer Interactive Toys: 

Can I Use Human Hair Shampoo to Wash My Dog?

Making sure your pet’s hygiene is up to standards is an important thing, but you have to be careful about how you go about it. There aren’t a lot of important rules to consider when doggo baths are considered, but you should pay special attention to the type of shampoo that you use. If you are all out of pet shampoo, and you are thinking that a little bit of human shampoo won’t make a difference – think again. Using human hair shampoo on your dog is not recommended, and the reasons for this are many, including negative effects on your pet’s overall health and the quality of their skin and coat. Here’s what you should know before you reach for your shampoo when bathing your pooch.Why You Shouldn’t Use Human Shampoo On DogsThe first and foremost thing you have to consider is pH balance. Human shampoos are formulated to match the pH level of human skin. However, that level is totally different for dogs. Because of this, human shampoo can greatly disrupt the natural pH levels of a dog’s skin, ultimately leading to rashes, irritation, and skin diseases. And the same goes for the ingredients in that shampoo.  Dog shampoos have totally different ingredients compared to human shampoos. The latter has many chemicals that are considered too harsh for dogs. Dogs are prone to skin allergies and sensitivities, and some of the ingredients in human shampoos could make these issues much worse. The allergies can also be triggered by the strong fragrances of human-grade shampoos, which dogs can’t really stand. You should also take into account that a dog’s coat and human hair are totally different. While human shampoos are meant to lather well on hair, they’ll be too soapy for dogs. Rinsing out human shampoo from a dog can be a challenge, and a lot of chemicals can stay trapped in the coat and absorbed through the skin. Ultimately, all of this can leave your dog’s coat damaged, their skin irritated, and their health vulnerable to viruses and skin-borne infections. 

Plumber's Hilarious Cat Rescue Mishap Goes Viral

It’s every cat parent’s worst nightmare—your cat escaping while work is being done at the house. Luckily for Winchester plumber Scott McKendry and his client, a recent alleged escape attempt had a happy ending. However, a Ring doorbell video of the plumber’s attempt to retrieve the cat has gone viral and inspired more than a few laughs! When arriving to work at a client’s house, McKendry was given strict instructions not to let the cat, Bertie, outside under any circumstances. You can imagine the fear and concern when he walked outside and discovered the cat casually strolling down the road. He quickly acted, catching the escapee and attempting to bring him back indoors. Unfortunately, the cat was less than enthusiastic about this plan. Unable to juggle both the unimpressed cat and the door handle, the plumber is forced to ask for help. It appears that all is well, with the cat safely home, when, in a hilarious turn of events, the door is opened to reveal Bertie already inside. That’s right! The entire ordeal centered around a completely different cat – Bertie’s doppelganger.

Vet School Aims to Dispel Misinformation About Mysterious Illness

News about a mysterious illness has been making dog parents across the country nervous as they seek out available information. While there have been reported advances made in understanding the cause of the illness, many of the details are still vague, and a lot of “data” being shared by the mainstream media seems to be contradicting. How do you know what to believe?To help clarify the sea of information, Louisiana State University School of Veterinary Medicine has published an educational hub on their website with information about the illness, Atypical Canine Infectious Respiratory Disease Complex (aCIRDC).This hub is divided into several categories: Prevalence, Clinical Signs, Pathogenesis, Screening, Treatment, Prevention, Travel, and News. The goal is to share reliable and actionable information for pet parents that will help them make smart, knowledge-driven decisions about their pet’s health, especially as we head into a busy time of travel during the holiday season.Reported Cases of IllnessAccording to the hub, there are currently reported cases of “a chronic respiratory disease with characteristics of aCIRDC” in 16 different states, including:CaliforniaColoradoFloridaGeorgiaIdahoIllinoisIndianaMaineMarylandMassachusettsNew HampshireNevadaOregonPennsylvaniaRhode IslandVermontWashingtonOne of the most important things to note is the wording used by LSU Vet Med. This list is based on reported respiratory illnesses that have characteristics of the mystery illness, but it does not mean that the disease itself has been confirmed. Many respiratory infections and ailments present with very similar symptoms, including Canine Influenza and Bordatella.How to Prevent Illness in Your Dog This Holiday SeasonWhile there is no guarantee that the above states pose a higher risk of aCIRDC, veterinarians and other professionals recommend that pet parents take precautions to keep their pets safe. This is especially important as many of us plan to travel and visit family for the holidays. The following recommendations (as outlined by LSU Vet Med) will help to prevent your dog(s) from getting sick from any respiratory ailment, not just aCIRDC.Ensure Vaccinations are Up to DateWe currently don’t have enough understanding of aCIRDC for a preventative vaccination, but there are vaccinations for some respiratory illnesses. Check with your veterinarian that your dog is current on all routine vaccinations.Limit Exposure (Where Possible)If possible, avoid or limit bringing your dog to areas that put them at a higher risk of contracting a respiratory illness. This includes dog parks or shelter environments. Have a conversation with boarding and training facilities where dogs socialize to better understand their preventative measures, including cleaning and sanitization efforts. You should also ask about the vaccine requirements for dogs in their care and their plan for handling animals that show signs of being ill.Isolate Dogs with Signs of IllnessIs your dog showing signs that they may be ill? If so, isolation is critical. Don’t bring a potentially sick dog to public spaces, and do your best to keep them safely isolated from any other unaffected dogs in your home.

What to Know About Cat Reproduction

With a better understanding of feline reproduction, you can take steps to prevent unwanted litters, and you’ll know what to expect if you have an intact female or male.What does it mean when a queen (intact female cat) is in heat? How long does a pregnancy last? And why does it seem that cats are so good at reproducing? Below are the basics to help you get started.  There Are Multiple Stages in the Cat Heat CycleA cat’s estrous cycle, also known as her heat cycle, consists of multiple phases. Also, females are seasonally polyestrous, so they can go into heat more than once throughout the breeding season.The stages of a cat’s heat cycle are:Proestrus – During this phase, which will last about a day or two, you probably won’t notice any obvious changes in your cat.Estrus – During this phase, which lasts about a week on average, a female cat will behave in a way that lets males know that she wants to mate.Interestrus – If a cat doesn’t mate, she’ll go into this phase, which can also last about a week on average, until she goes into proestrus again. If a queen mates, ovulates, and becomes pregnant, she will enter diestrus.If a queen isn’t in a heat cycle at all, she’s in anestrus, which can last months.Cats Can Get Pregnant When They’re a Few Months OldCats become sexually mature around 6 months of age, on average, but it can happen even sooner than that. For example, a female can go into heat when she’s a mere four months old.This means that even kittens can mate and get pregnant. If you have intact male and female kittens, this is definitely something to be aware of. Talk to your veterinarian about the best time to spay or neuter your feline companions to prevent unwanted pregnancies. Cat Pregnancy Is Roughly Two Months LongA cat’s pregnancy can be shorter at 60 days or longer at 71 days. On average, a cat will give birth in about nine weeks, or 63 to 65 days. In other words, the pregnancy will be roughly two months long.On average, a cat will have four kittens, but she might have just one or she might have six or more. A queen’s age may affect the size of her litter—for example, a cat who’s pregnant for the first time is more likely to have a smaller litter, as is an older queen.After giving birth, a cat might go into heat again sooner than you think. It might even happen while her kittens are still nursing. So, if you’re caring for a mother and her litter, it’s important to prevent another pregnancy by keeping her safe indoors and away from intact males. Cats Are Induced OvulatorsWhat’s interesting about cats is that they’re induced ovulators. Put simply, when cats mate, the female ovulates, releasing eggs from her ovaries. And since the eggs are released with mating, it times out in a way that boosts the odds of pregnancy.A queen typically needs to mate multiple times before eggs are released, and she could mate with more than one male while she’s in heat.  A Litter of Kittens Can Have Different FathersAs mentioned above, a queen will mate more than once while she’s in heat. Well, another interesting fact about cats is that they can mate with more than one male while they’re in heat, so they could end up with kittens that have different fathers.In other words, a single litter of kittens could have two or more fathers. This is known as superfecundation.There Are Several Signs of Pregnancy in CatsHow can you tell if a cat is pregnant? Even though there are going to be several signs as the fetuses develop, you might not notice anything right away.You might first notice the queen’s nipples becoming more obvious. This is followed by weight gain that will eventually cause her belly to be big and round. Changes in behavior are also often seen in pregnant cats. Her appetite will increase, she may become more needy and affectionate, and she’ll look for a nest where she can give birth safely and comfortably.If you are caring for a pregnant cat, consider getting a product like the Sport Pet Pop Open Pet Kennel, which features two entryways, has a waterproof bottom, and comes with a removable, machine washable pad. She might view this as the perfect nesting box, and you’ll feel good knowing she’ll be secure in there with her kittens.

Check Out Giant Dogs On the Free 2024 Calendar of the Portland USACE

Who knew that calendars featuring gigantic cats could be such a hit! Last year, the Pacific Northwest-based U.S. military personnel issued their own calendars which featured enormous kitties that oversaw construction projects making a seemingly ordinary calendar - a ton of fun. Needless to say, their hilarious (and completely free) calendar went viral, so they wanted to repeat last year’s success. This year, however, the Portland branch of the US Army Corps of Engineers, which is based in Oregon, decided to “branch out”, and their new yearly 2024 calendar will feature gigantic doggos as well. This was a logical follow-up to their viral social media campaign of the previous year, when kittens stole the show. The personnel of this military branch handles tough civil works in the whole of Oregon and southwestern Washington, so a bit of lighthearted humor really goes a long way for them. Their staff got the idea of superimposing photos of cats and dogs into quality landscape photos of the most important public infrastructure projects that the teams were involved with. The idea was an instant hit. And now, their 2024 calendars in both cat and dog editions can be freely downloaded in a PDF format, allowing quick and easy printing. You can find the dog calendar here and the cat calendar here.“This product was created to tell the story of our district and what we do in a way that’s actually enjoyable for the average member of the public,” Portland district spokesman Chris Gaylord said. Mr. Gaylord further said that the whole project was their effort to portray an otherwise rough and industrial work in a more entertaining light. And it is also a way for the workers to get some steam off as well. After all, they are busy throughout the year, operating more than 700 dams and 12,000 miles of inland waterways. “It was really so inspiring to see how much joy this little product brought to people all over the world,” Gaylord said, after their first calendar “won over the internet”, getting an incredible 530,000 downloads on their website. To make matters even more memorable, the photos of the pets are from the employees themselves! Gaylord received almost 750 photos from 150 workers. Choosing just a few to include in the calendar was no easy task. But to make everyone satisfied, a page at the end of the calendar includes a grid with most of the pets that did not make it onto the big pages.

What is Red Light Therapy for Dogs?

When your dog gets injured or is recovering from a routine surgery, it can be difficult to keep them comfy and to help heal their injuries faster at the same time. However, innovative red light therapy for dogs proved to be a safe and efficient treatment for a variety of ailments, from skin inflammation to wound healing, and much, much more.Red light therapy is also known as photobiomodulation therapy, and it involves the use of red or near-infrared light to stimulate healing and reduce inflammation. The reason for its effectiveness is the specific wavelengths that are absorbed by the mitochondria in cells, which are considered the cell’s powerhouse. As the mitochondria absorb the “red light”, the absorption stimulates the production of adenosine triphosphate (ATP), which is popularly called the “energy currency of cells”. The entire process then increases blood flow to the treated area, stimulating faster healing, and pain relief. What’s so great about red light therapy is that it is not invasive, and all that is needed is a specialized device that emits specific wavelengths of light.Red light therapy treatment sessions usually last from a few minutes to around 20 minutes, depending on the condition being treated and the specific device used. The frequency of sessions may vary, with some dogs benefiting from daily treatments initially, followed by less frequent “maintenance” sessions. Of course, your veterinarian can advise you on the appropriate treatment procedure for your dog's needs – if you’re unsure if red light therapy is the right choice for your dog, be sure to consult an expert before taking any steps.Of course, while you shouldn’t do anything without your vet’s approval, a great thing about this treatment is that it is entirely safe. When used appropriately, it has no risks for your dog. The secret is in the light energy that does not generate heat at all, eliminating any risk of burning or tissue damage. Naturally, it goes without saying that you should closely follow the manufacturer’s guidelines for the specific device you are using.
