study exposure to cats can reduce childhood asthma rates

New research suggests that a cat in the house around newborns can help prevent children from developing asthma.

Researchers from the Copenhagen Studies on Asthma in Childhood Research Center (COPSAC), Denmark, are suggesting that cats can prevent asthma from developing in children.

The scientists concluded that cats neutralize the effect of a specific gene in our body. When this gene is activated, children have double the risk of developing activated. They believe that if a cat is in the home when the child is born, the gene is never activated, and the risk of asthma decreases significantly.

Hans Bisgaard is a professor of pediatrics and the head of COPSAC. He is also the lead author of the study and he says that he was surprised because the study showed that genes connected to diseases can be basically switched on or off like a light based on the environment we are in.

He says that it shows how the connection between our genetics and the environment is so important, and in particular, how important our environments are in pregnancy and a child’s early life.

The study looked at 377 Danish children whose mothers had asthma–looking at their mapped genes and information about their environments and upbringing with both surveys and samples. They found that cats removed the risk of asthma developing in children who had a specific variation of the gene 17q21, also called TT. This gene has the strongest impact on whether the children would develop asthma or not and almost one in three of the children carried the TT variation gene. Their mother having asthma or not had no bearing on that statistic.

The scientists found that only cats seemed to make a difference in the development of asthma in children who had the TT gene variation, and exposure to dogs early in life did not have the same effect. More, they also believe that cats helped protect against asthma and bronchitis, as the 17q21 gene is connected to those conditions.

Because these results show that genes and the environment interact so precisely and yet in such unknown ways, it’s important for more research to be done to look at the broader implications. Particularly because the study doesn’t show exactly what it is about cats, and whether it is cat specific, that helps protect children with those gene variations, the researchers would like to know exactly what kind of and how much exposure to cats early on would make an impact.

Co-author Jakob Stokholm believes that it could be something in the bacteria that cats carry or something about fungus or viruses specific to cats that children are then exposed to that can influence the immune system. Stokholm says that this could lead the way for finding more about how to protect children from developing asthma altogether.

New Research Suggests Dogs Help With Eczema and Asthma in Children

There are many benefits to having a dog as a family member, but two new studies are suggesting pets may also protect children from developing eczema. Dr. Gagandeep Cheema is an allergy and immunology fellow at Henry Ford Hospital in Detroit, Michigan. He led a study that suggests having a dog in the house prenatally may help your child keep eczema away, at least until they are in their toddler years. Dr. Cheema says that the disorder, which is characterized by dry, flaky and often unsightly patches, is typically a sign of an allergic condition, though research shows that allergic reactions do not always cause eczema. He and his colleagues looked at the data from 782 mothers and their children, particularly looking at prenatal exposure to dogs, and more specifically, where a dog spent at least an hour a day inside the home. Related: Study: Dogs’ Immune Systems Leave Them Vulnerable As They Age They found that when they compared children whose mothers had that prenatal exposure to dogs to children whose mothers did not, the risk of eczema was about half as high as in the children with no dog exposure. The data seemed to suggest this may have equaled out by age ten, but Dr. Cheema says continuing research and data gathering might change that suggestion. Another study looked at people who lived with dogs, and asthma symptoms they believed were associated with substances found on their dogs. Dr. Po-Yang Tsou is with Johns Hopkins University, and he and his colleagues looked at 188 asthmatic children from Baltimore. They found that the non-allergen substances on dogs (like bacteria or dirt) seemed to take the need for an asthma inhaler down, and even reduced symptoms of asthma at night, while exposure to allergen-producing substances from dogs (like dander) increased the need for inhaler use, as well as increased nighttime asthma symptoms. Dr. Tsou said that in urban children with asthma, particularly those allergic to dogs, spending time with a dog may be different based on the dog’s coat. In children who are allergic to dogs, obviously, exposure to dogs could be dangerous. However, it seemed that there was a protective impact on asthma when the children were exposed to dogs with non-allergen substances (like dirt) and a harmful effect when the substances were allergen-producing (like dander). Related: Study: Exposure to Cats Can Reduce Childhood Asthma Rates Dr. Cheema said that while research is still new, and it’s too early to tell people to increase exposure to dogs so they can prevent allergic issues from happening, he does say that for those who have dogs, it’s fair to say that their research shows the dog may protect the children in the home from asthma. Current research shows that children who have exposure to dogs benefit because it affects their microbiome positively. He said the more research they do on dogs, the more they realize how much dogs assist us, and how close our relationship is.

New Study Shows Surprising Effect of Pet Ownership on Seniors

You’ve probably noticed how your four-legged bestie influences your mood for the better, but did you know that your pet might be beneficial to your brain? That’s right! The latest studies show that your pet and their company could be just the thing to lower the risk of dementia in your golden years. These findings are especially important for single senior pet owners who are at risk of this troubling illness as they reveal that having a pet can make a drastic change. A recent study that involved adults over the age of 50 who lived alone revealed that those living in the company of a loved pet will have considerably less decline in their verbal fluency and verbal memory - compared to those who lived without a pet. This research was published in the  journal JAMA Network Open and was based on data taken from 7,945 people in the mentioned age group.This study, however, only reflects on people who live alone and does not involve participants who lived with other persons in the household. Still, while the results reinforce the fact that loneliness is a major risk factor for cognitive decline and dementia in old age, they also reveal something new – that the company of a pet counts as much as the company of human family members, if not more so.The early signs of cognitive decline can be fluency, verbal issues, cognition, and memory problems, and so on. But if you have the company of a pet, whom you can address and care for, can greatly reduce the feelings of loneliness and keep these cognitive issues at bay. This study and its results are very important in today’s day and age and for many Americans in particular. Recent U.S. Census Bureau insights revealed that almost 28 percent of all households in the United States were “one-person households” in 2020. This is an alarmingly large number and shows us that many people aged 50 and older will face lonely senior years. Of course, even though the results of this study show that older people can maintain their mental health through the company of a pet, the research team emphasized that more advanced studies and clinical trials will be required to fully confirm the results. Yet even so, the lack of an effective therapy that can reverse or slow cognitive decline and treat dementia means that these results are a small but very important benefit for the understanding of these issues. And, needless to say, all those who are entering their senior years and want to spend them in a healthier and more beneficial way now know that their next station should probably be a local pet shelter. Find a pet you can love and cherish - and keep your brain healthy while showering them with affection.

“One-of-a-Kind” Cat With Two Noses Searches for Her Forever Home

As rescue cat parents and rescue advocates, we know firsthand that every cat has a unique story to tell. But some cats truly stand out and make their mark on the world. Nanny McPhee, a rescue cat who recently came into the care of the Cats Protection Warrington Adoption Centre. It’s not the way this sweet girl came into the shelter or her life before that has everyone talking… It’s a VERY unique physical feature – her nose, or “noses,” in her case! The sweet kitty lived in a loving home for the first four years of her life. Unfortunately, her previous owner had to make the difficult decision to contact a rescue due to health and financial reasons. When Nanny McPhee first arrived at the rescue, volunteers and rescue workers noticed a few things about the tuxedo kitty. First, she was a very gentle lady with a love for attention.“She has proven to be a gentle lady who adores a fuss and a cuddle, and we are hopeful her new-found fame will mean she will have no shortage of potential adopters,” shared shelter manager Lindsay Kerr. “She really does deserve a home where she can settle down and become the center of a loving family.” Second, they noticed she had a surprisingly large nose. It was this unique feature that led to her being named after the popular children’s character. But that signature sniffer was hiding an even bigger secret. A check-up with a local veterinarian revealed that the cat had not one but TWO noses, creating the appearance of one large snout. When asked about the discovery, senior field veterinary officer Fiona Brockbank explained that it was the first time they had seen this but that the cat’s unique appearance resulted from a congenital malformation. Other more common examples of this include cleft palates or cleft lips. These conditions can be inherited or caused by an incident during development in utero.

Is Melatonin Safe For Dogs?

Melatonin is an important hormone, which is naturally produced in the pineal gland of the brain. It has numerous beneficial aspects, such as it can help regulate mood, sleep cycles, and reproduction. However, its production is directly stimulated by darkness, while it is inhibited by light. What does this mean? It means that both dogs and humans will produce melatonin only when it is dark outside. As soon as the dawn arrives with the light of day, melatonin production ceases. This means that many people will supplement melatonin, or use it throughout the day for various reasons. Which brings up the question - is melatonin safe for dogs? Let’s find out. Is Melatonin Safe For Dogs? Melatonin is generally considered extremely safe for dogs, and it is almost always safe to give it to them - when it is used appropriately and under the guidance of a veterinarian. While melatonin is used in humans for the above-mentioned reasons, for dogs it is usually used for treating various skin conditions, anxiety, or sleep disorders. But even with all the positive aspects, it is necessary to first heed the advice of your veterinarian, before giving melatonin to your pet. This is because the proper dosage is important. The dose of melatonin administered depends on your pet’s size, weight, and overall health condition. Generally, veterinarians recommend starting with a low dose and gradually increasing it if necessary. Dosages typically range from 0.5 to 3 milligrams per dog, but this can vary. Mistake the dosage, and you risk a lot of side effects, like digestive upset, lethargy, and changes in mood or behavior.What is more, melatonin might not be suitable for dogs with certain health conditions or those taking other medications. Because of this, it is always crucial to seek professional advice before administering any supplements or medications to your pet. Ignoring this can cause a lot of harm.

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 do you think – which pooch of the month is your fave?

Dave Bautista Teams Up With the ASPCA for Giving Tuesday

With an estimated 3.1 million dogs entering U.S. animal shelters every year, the need for funding and support is evident. For many, this is a call to action to find ways to make a difference – including for Guardians of the Galaxy actor Dave Bautista. Starting today, November 28th, the American Society for the Prevention of Cruelty to Animals (ASPCA) is launching a new fundraising and awareness campaign with 54 Bautista and his four rescue pit bulls in the spotlight. The campaign was created as part of Giving Tuesday, a global response to the corporate focus of Black Friday (as well as Small Business Saturday and Cyber Monday). Rather than highlighting sales and taking advantage of deals through your favorite stores and brands, Giving Tuesday encourages Americans to take a moment and consider how they can make a difference in the lives of others – including, of course, animals in shelters and rescue organizations. Bautista’s involvement in the campaign is motivated by his experiences with animal rescue and its impact on his life. “My home is where my dogs are because there is just such a sense of love,” Bautista stated. “I feel like wherever they are, there’s this sense of normalcy, which is hard for me to attain these days.” He went on to explain, “My first rescue dogs were Ollie and Maggie, and I’ve had them for about five years. I adopted them, and after becoming so connected with them, I started to be more aware of how many dogs are just waiting for someone to give them good, loving homes. You get so much in return when you adopt a pet, and I’m going to preach adoption for the rest of my life.”

After 11 Long Years, a Cat That Was Presumed Dead Returns Home

Sometimes, miracles can truly happen when you least expect it! And if a pet story can be considered a real life miracle, it’s the one about Toby, a family cat that - it would seem - lived a life of great adventure. In 2012, Toby, the now 14-year-old cat of the Allan family from Warwickshire, suddenly disappeared after the family moved to a new house. It was a heartbreaking event for the entire family, but their pet was nowhere to be found. After many attempts to locate their cat, they simply had to come to terms with the fact that old Toby was lost, and presumably dead. But this week, after 11 long years, Toby was returned to the Allan family by a local woman. The lady checked the cat’s microchip and was quick to get in touch with Coventry Cats Protection."I never thought in a million years I’d see him again," said owner Justine Allan. "Toby was collected and will no longer have to scavenge for food and sleep in a cold bin store," added the Coventry charity co-ordinator Wendy Harris.Toby suddenly went missing in a chilly December in 2012, after the Allan family moved from Galley Common in Nuneaton, to their new residence at Long Shoot."[My son Charlie] was about 12 when Toby went missing, and he was heartbroken when we realized he probably wasn’t coming back," said Mrs Allan for  Yahoo "The Long Shoot is a notoriously busy road, we just assumed the worst had happened and thought he had been run over.”But almost a decade later, just 5 miles away a local Bedworth lady got in touch with Cats Protection, believing that a stray cat she was feeding was pregnant. A volunteer with the charity went out to investigate, a microchip scanner in tow. "It turned out, not only did it have a chip, but that he was a neutered male named Toby, rather than female as originally believed," said Ms. Harris.Blazingly fast, the charity managed to trace the details of the Allan family on their database, and got in touch to share the splendid news – their missing feline friend was re-discovered!Initially in complete shock, after 11 years, the Allan family rejoiced and celebrated and quickly went out to pick up their long-lost pet. During those 11 years, the family welcomed another pet into their home, a King Charles Cavalier named Bernie. But even so, Toby fits right back into the family dynamic. As if he wasn’t missing for more than a decade!

Study Shows Shape of a Dog’s Head Can Actually Affect Their Sleep

If you have noticed that your dog’s sleep quality is reduced, or that they have begun to snore heavily, there might be an unusual reason behind it – the shape of your pet’s head! Snoring problems can be quite common for many dogs, but they are most often seen in brachycephalic dogs – basically, dogs with flat faces. For example, this is the key characteristic of the  French Bulldog, one of the world’s most popular breeds. In the USA, and in Hungary where the research for these claims was conducted, the goofy little French Bulldog holds the place of the number one most common pet dog breed. And that means that some health-related issues, stemming from their flat-face appearance, are coming into the foreground. Their shortened skulls and brachycephalic morphology result in sleep problems, snoring, difficulties with breathing, and deteriorative brain morphology changes. According to the latest  study by a Hungarian research team, flat-faced dogs tend to sleep more because their breed suffers from sleep apnea and thus their daytime sleepiness is increased. Thus, their REM (deep) sleep phase is much longer than their non-REM sleep, while the EEG patterns in their sleep indicate signs of white matter loss. And while some owners across the world see these Bulldogs and their extremely flat skulls as an attractive or unique feature, it is, nonetheless, a major health hazard. These breeds, for example, the French Bulldog, the Pug, and the English Bulldog tend to live around 3 to 4 years less than other dogs, and in many cases, they don’t even live to adulthood.Some will even have to undergo surgery to correct their musculoskeletal, respiratory, and eye problems, which can cause them a lot of problems throughout their lives. To make matters worse, the rounded and short skull of these dogs results in a distorted and rounded brain, which could affect neural functioning.All this resulted in the Hungarian team’s extensive research into the sleep of these breeds. They studied the sleep of 92 dogs, using EEG. "In the sleep lab, dogs spend about three hours with their owners. As nothing exciting happens, the dogs fall asleep quickly. Meanwhile, we conduct the electrical potential generated by the brain activity with electrodes glued to their scalps," says Anna Kis, who is considered a pioneer in the study of sleeping dogs and a researcher at the HUN-REN Institute of Cognitive Neuroscience and Psychology. "We wanted to investigate whether flat-faced dogs sleep differently from other dogs, as they are known to suffer from oxygen deprivation due to respiratory problems and therefore have poorer quality sleep. We found that the flat-faced dogs slept more in the three hours given to them during the study. More daytime sleep is probably compensation for insufficient sleep at night.”Ivaylo Iotchev, the first author of a study of dog sleep patterns that was published in the Journal of Brain Structure and Function, adds "In the present study, we found that brachycephalic dogs had decreased beta waves and increased delta compared to dogs with longer noses. The frequency of sleep spindles increased. This pattern has previously been associated with poorer learning in dogs and loss of white matter in humans."He also adds "There may be several reasons for our results. The most interesting of these is that it seems as if the flat-faced dogs have retained the sleep pattern of puppyhood, similarly to newborns who spend more time in REM sleep.”If you own a brachycephalic dog and have been seeing a lack of quality in their sleep, these studies might provide the answers you are looking for – your pooch’s genetics might be to blame for their poor sleep.

Does Your Dog Have What it Takes to Be a B.A.R.K. Ranger?

Is your dog your favorite adventure buddy? Do you dream of exploring America’s National Parks system with your furry best friend by your side? While many parks have limitations on where dogs are allowed, the popularity of pet-friendly travel is on the rise. In response, the U.S. National Park Service introduced a program to teach dog parents how to travel with their pups responsibly – the B.A.R.K. Ranger Program. But does your dog have what it takes to be a B.A.R.K. Ranger? What is involved in earning that title anyway? In this article, we will break down the B.A.R.K. principles and why they are so important for responsible outdoor travel. We will also share tips for helping your dog become a certified B.A.R.K. ranger. What Does the Acronym “B.A.R.K.” Stand For? Let’s start at the beginning—what exactly is the B.A.R.K. Ranger program, and what does the acronym “B.A.R.K.” stand for? Recognizing that a growing number of dog parents wanted to bring their pups with them when visiting the parks, the U.S. National Park Service recognized a need for education on how to travel with dogs responsibly. This means focusing on the importance of respecting the environment, local wildlife, and other visitors to the park. This program is a partnership between the National Park Service (NPS) and the Association of Pet Dog Trainers (APDT). It is part of the Healthy Parks Healthy People Initiative, which is focused on the idea that “parks can be gateways to good health – for people and the planet.” The B.A.R.K. acronym stands for: B – Bag your pet’s wasteA – Always leash your petR – Respect wildlife K – Know where you can goThe concept is similar to the traditional Leave No Trace principles but focuses on how a dog may impact the environment and the overall park experience. What Are the Qualifications to Become a B.A.R.K. Ranger? The good news is that the requirements to become a B.A.R.K. Ranger are very broad. The program is open to dogs of all ages, breeds, sizes, and activity levels. From the senior chihuahua who prefers to be carried along the trail while still enjoying the fresh air to the high-energy Border Collie who could hike for days without stopping, all are welcome! So, does your dog meet the qualifications? As long as they are dog – YES!What is the Process of Getting Your Dog’s B.A.R.K. Ranger Certification? This is where the conversation becomes a little more complicated. While the B.A.R.K. Ranger program is a National Park Service program, the exact requirements to be named a B.A.R.K. Ranger vary from park to park. This allows each park to customize the program to best suit its area and the needs of those who visit each park specifically. At some parks, you will be asked to take a booklet and fill it out. Once you have completed the booklet, you will receive your commemorative leash tag. At other parks, a program is offered that you will attend to learn more about the B.A.R.K. principles and how they can be applied in your travels. Finally, some parks make it incredibly easy. They ask those interested to learn about the B.A.R.K. principles at home before coming to the park. Upon arrival, the dog's parents are asked if they understand and agree with them. They then take a pledge to follow these principles before their dog is given the coveted title.

Do Dogs Cry Tears?

Perhaps you spotted tears streaming from your pet’s eyes and wondered: do dogs cry tears as an emotional response? Or is there a different explanation for this phenomenon? Well, the answer is pretty straightforward – dogs don’t produce tears because of their emotions like we humans do. They produce tears primarily to lubricate their eyes, and remove dust and other irritants. But, this does not mean that they don’t express emotions in other ways – here’s what you need to know about your teary-eyed furball.Do Dogs Cry Real Tears?If you spot tears running from your dog’s eyes, you are not deceived – they are real. However, they are not tears of sadness or emotion, as dogs simply don’t express feelings the same way as we do. The role of those tears is more of a bodily function. They are there to lubricate the eye, making sure it functions as it should. After all, dogs can just rub their eyes or place a few drops inside when needed. So, their body does the job for them, and hence the tears. Of course, an excessive amount of tears is not natural. And neither are dry and tearless eyes. So, in either one of these cases, you should schedule a visit with your vet. Dry eyes in dogs are also known as keratoconjunctivitis sicca (KCS) or "dry eye syndrome," and can lead to discomfort, irritation, and potential complications if left untreated. In many cases of dry eyes, veterinarians prescribe artificial tears or  lubricating eye drops to help moisturize the eyes and relieve discomfort. These drops can help supplement the natural tear production and provide relief from dryness. 

Once-Abused Dog Celebrates First Christmas With Vet Who Saved Him

A puppy who survived a terrible beating has celebrated his ‘first proper’ Christmas with a veterinarian nurse who provided a loving furever home for him.A whippet named Terry was only 12 weeks old when he was viciously attacked by his owner and left with severe trauma injuries after he urinated inside. The injured pup was taken to the Hull PDSA Animal Hospital in East Yorks, England, where he was treated by the veterinary nurse Rachel Coombes. During the initial exam, the hospital’s staff discovered that Terry had a bruised eye and lips. The pup was also missing three of his upper incisors, and another tooth was broken.For nurse Coombes, this was love at first sight! She told her colleagues that if Terry survived, she would adopt him, and that’s exactly what she did.Although Terry celebrated Christmas with Rachel and her son Stanley last year, this year was their ‘first proper’ Christmas together since Terry is now fully settled in with the family.“I just felt a connection as soon as he was brought in as he was in such a state we actually thought initially that he hadn’t made it,” said nurse Rachel according to Talker. “Then when we spotted gentle breathing I did say ‘if he survives this I’m going to give him home’ which is exactly what I did.”From that moment on, Terry’s life changed completely! “He hasn’t looked back since - he loves life and is having the best of life right now.” According to his new owner, Terry likes to run around the garden and enjoys going to the beach. The pooch has also formed a strong bond with Rachel’s son, Stanley, and is always by his side. “Last year, we got him around Christmas, but it was such a hectic time for him, and he was learning to settle then.” But this year, the family planned a festive celebration for Terry and did everything to make him feel special during the holiday season. Due to the suspicious nature of Terry’s injuries, RSPCA Inspector Laura Barber was asked to investigate. The inspector said that despite the severity of his injuries and his overall state, Terry had put his head on her and was so trusting. “He was in such a sad state and was really quiet and withdrawn when he was with people. He was so lovable, and it is great to see he has a home he deserves with such a lovely family.”“I know Terry will have the best first proper Christmas with his lovely new family and one he thoroughly deserves,” the inspector added. Terry’s extensive injuries were enough to build a case against his former owner. After appearing in court and admitting to causing unnecessary suffering to a dog, the person was handed a five-year ban on keeping animals. Emily Lomas, an animal care assistant at RSPCA’s Hull branch, said she was thrilled when she learned that Rachel had adopted Terry. “He was very traumatized and overwhelmed when he came to us, we had to really show him there was nothing to be scared of and that he was now safe. We took him to the socialization room, and I remember him falling asleep on my legs,” said Lomas.“We were all thrilled when he was adopted and knew he was going to a special home,” she added.Join the PetGuide community.

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.

Signs a Dog Is in Pain

Don’t you wish your dog could talk to tell you how he feels? After all, it can be tough to figure out if your pet is experiencing discomfort. But if you learn more about your canine companion’s body language, you’ll be able to pick up on the signs your dog is in pain. Below are some of the things to watch out for.

Newfoundland Dogs Deliver Your Tree at This US Christmas Tree Farm

“It’s a great way to expose people to the joy of Christmas but also teach people about Newfoundland dogs,” explained Lindsay Eshelman when asked about her family farm. “They’re big, and sometimes people are scared of big dogs, and we want to show that they’re gentle giants.”The Esheman family’s love of the breed is evident, with four Newfoundland dogs currently among their ranks. But they didn’t want to stop there. By inviting Newfies from far and wide to come together, they have rightfully earned the title “The Newfoundland Farm.” The event has become a big part of what they do, a tradition they excitedly look forward to year after year.“We are a destination for these dogs,” Eshelman said. “We actually have had people drive all the way from Vermont, Maine, Ohio – those are ten-plus hour-long drives.”Are you interested in joining the festivities next year, but your dog doesn’t quite fit the breed? Don’t worry! Their Facebook states that all dogs are welcome, not just Newfies. If your dog isn’t keen on public spaces, that’s okay too! Dog lovers are welcome to join in with or without a dog. There will be plenty of adorable pups eager to enjoy your attention.So, start planning your trip to Pennsylvania next year to participate in Newfoundland Day and make some unique holiday memories.Join the PetGuide community.
