When it comes to fleas, you want to keep them in their place – and off your kitty and home! For control you can count on, check out our list of the best cat flea collars.

Keeping fleas off of your cats, and out of your home, is important, but it’s equally important to find a product that will repel and/or kill fleas in a safe and effective manner. After all, there is nothing so pesky and annoying as fleas! These little micro critters are the bane of every cat and dog- not to mention their owners. Appearing seemingly out of nowhere, they can become a true nuisance and cause irritation and further issues through excessive scratching and your pet’s search for relief. Thankfully, fleas can be controlled with a whole host of remedies, and flea collars are some of the best solutions out there.

In addition to flea products that are designed to be taken orally or applied topically, flea collars are an option that many pet owners turn to. They aren’t all created equal, though, so we have compiled a list of 10 of the best flea collars that are currently available, and that you might want to talk to your veterinarian about using on your cat. Check them out below, in no particular order. Relief is a click away!

But First, A Note About Flea Collar Safety

Keep in mind that some of the ingredients that are used on flea collars might be detrimental to your pet’s health, as well as to human health, so it’s wise to consult with a veterinarian and do your own research before selecting the right product for your pet. Luckily, plenty of brands rely on tried and tested ingredients that will cause no side effects or reactions. Of course, all natural flea collars are very rare, as the ingredients need to be potent enough to deter those elusive fleas. Still, with a reliable balance of ingredients used, efficient control and no side effects are guaranteed.

According to WebMD, the Natural Resources Defense Council (NRDC) reported that some over the counter pest control products made for pets contain ingredients that might be harmful. They also discovered that high amounts of pesticide residue might stay on a kitty’s fur for weeks after you put a flea collar on your pet, and that may pose a risk to humans as well.

When shopping for your pet, it’s best to search for flea products that have been proven safe, that have received a lot of positive reviews from customers, and that are recommended by vets. Don’t let price be the only factor when selecting your cat’s flea treatment, and keep in mind that some essential oils might be harmful to felines as well, so even “natural” products might not be the ideal choice. Then, once you’ve made your selection, follow the directions on the package closely to be sure you’re using the product correctly.

Also, read through any information that a manufacturer has provided about their flea collar. This includes not only how to use the product safely and correctly, but also what adverse reactions and side effects to watch out for. Keep an eye on your kitty after you put the flea collar on her, and if your cat ends up experiencing any side effects, remove the collar and contact your veterinarian right away for advice on what to do next. Still, don’t let all these factors deter you: most brands nowadays rely on solutions and ingredient combinations that are totally safe for your cat. That means that with proper use and for a certain period, a good flea collar will help solve the issue with no harmful side effects!

Some Flea Collars to Consider for Your Cat:

1. Editor’s Choice: Seresto 8 Month Flea & Tick Prevention Collar for Cats & Kittens

Fleas don’t even need to bite your kitty before they are affected by this flea medicine. The formula is water-resistant and will keep on protecting your pet even after bathing and sun exposure.

This is an odorless and non-greasy flea collar that contains two active ingredients. They are imidacloprid, which controls flea infestations, and flumethrin, which repels and kills larvae, nymphs, and ticks. These ingredients are found inside a polymer matrix that allows them to work together and provide protection for up to eight months.

This flea collar is designed to be used on kittens and cats of all weights, but they need to be 10 weeks or older.

Basically, you increase the length of time that the collar is worn before you put it on your kitty for continuous wear. That way, you can see if adverse reactions occur and if you need to stop use of the product.

Keep in mind that this collar will only be able to repel fleas, so this might not be the right product for you if you are searching for something that will kill fleas.

Even though the manufacturer claims that this product is safe for humans and pets, and that it can work well on cats that have sensitive skin, it is always best to follow the directions on the packaging closely and keep an eye out for any adverse effects anyway. After all, every kitty is unique, so your pet might react to a flea collar differently than another cat would.

8. Best Botanical: Arava Flea & Tick Prevention Collar

The active ingredients in this flea collar can repel nearly 500 species of insects. Ingredients include geranium oil, clove oil, citronella oil, rosemary leaf oil, castor seed oil, cedarwood oil, peppermint oil, and thyme oil, among others.

Basically, the scent that is released by the essential oils works on repelling fleas and ticks, so it might work well at preventing an infestation. As an added bonus, most of the ingredients above have a natural basis, which is a welcome change from chemical flea deterrents.

9. Best Eco-Friendly: Petsvv Cat Flea Prevention Collar

10. Honorable Mention: Only Natural Pet EasyDefense Flea, Tick & Mosquito Dog & Cat Collar Tag

Something a little different is the Only Natural Pet EasyDefense Flea, Tick & Mosquito Dog & Cat Collar Tag, which is based on years of research. Unlike traditional flea collars that contain synthetic or natural ingredients which can give off slight scents and odors that bothersome pets and their humans, this is a tag that you can place on your cat’s collar to repel insect pests like mosquitoes, ticks, and fleas naturally, without the use of any pesticides, oils, radioactivity, magnetics, chemicals, or electricity.

This tag contains silicon dioxide particles that have been encoded with frequencies that deter insects. After you set the tag on your cat’s collar, the frequencies are emitted to repel pests. The protection can last for a full year, and this product is considered safe for animals and humans. However, the protection starts three weeks after placing the tag on your pet’s collar, so you do need to be patient at first. You may want to purchase another type of flea and tick collar like the ones listed here to be used in the meantime.

Also, this product is scientifically proven, but it only really works at repelling fleas- not getting rid of an infestation. So, if your cat already has fleas, this tag might not be able to help on its own, and you will likely need to use another product to get rid of the fleas that are already there. On the other hand, if there aren’t any fleas and you want to prevent an infestation, this tag might be worth trying if you want to take a natural approach. After all, it is a smart and modern design that really changes the way we experienced flea collars until now.

Remember to Shop Wisely for Flea Collars for Cats!

Hopefully, this list will help you as you start looking for the right flea product for your furry friend.

Whatever your choice, effects should be pretty fast to observe – and relief for your furry four legged friend is fast approaching!

As mentioned above, however, keep in mind that side effects and adverse reactions might be possible, especially when a product is not used as directed. If you choose carefully, though, you should not be worried about dangerous side-effects. In the end, most cat flea collars on the market today are totally safe to use for a certain period of time, and will in the end prove to be an invaluable helping hand for your cat. And, as always, when in doubt, consult with your cat’s veterinarian to figure out which path you should take in order to keep those pesky fleas away. After all, your vet knows best – they can often be the voice of reason and recommend one of the established brands and an efficient flea collar for your pet. Remember that their advice is always helpful- and the most reliable you can get.

Either way, cat flea collars are a modern, tried and tested way of dealing with the reappearing flea infestation problem. It is one of the simplest and quickest ways to offer relief for your itchy friend, and also one of the most affordable ways to do so. It might not be the most natural way to deter fleas, but it is nonetheless super effective – as proven by millions of happy kitties that live their lives free of fleas! Still, if you find that the flea problem has turned into a proper flea infestation, collars might not be enough, and you will need to find a permanent, professional solution. Until then though, one of these nifty accessories will be an ideal solution.

When should a cat wear a flea collar?

It all depends on the manufacturer and the formula used for the flea collar, but most flea collar for cats are safe for kittens over 3 months or 12 weeks of age. Before using one, though, be sure to check the specific instructions on recommended age for use. A flea collar should be used from a young age, both to allow your pet to get used to wearing one and to provide early protection from blood-sucking parasites, as fleas don’t discriminate: they can attack even newborn kittens.

Which is better: flea collar or drops for cats?

It all depends on your preference. Collars usually offer longer protection, lasting up to several months, whereas drops offer a few weeks of protection, usually under a month mark. However, some cats don’t like wearing collars or lose them all the time, so they can’t be an option – this is where the drops come into play. Before deciding on a flea-repelling product, be sure to research all your options and get the option that will best suit your cat’s individual needs – after all, all kitties are unique!

Do flea collars work if my cat already has fleas?

Some will, some won’t – it depends on the formula. Some cat flea collars are designed to only repel fleas, not kill them, so they are used as a preventative on pets that don’t already have fleas, or after the fleas were eliminated with another method previously (e.g. flea shampoo or drops). Of course, there are also more potent flea collars for cats that will both kill and repel fleas, so if you want a 2-in-1 solution, go for one of these.

How do you put a flea collar on a cat?

The same you would any collar, with one difference – cutting it down to size. You should place the open collar on your cat’s neck, thread the collar through the buckle/loop until it fits comfortably, meaning you can fit two of your fingers between your cat’s flea collar and their skin. The collar shouldn’t be too tight but not too loose, either, as it can slip off. Once you have a good fit, you should use the scissors to cut the remaining collar pieces (anything an inch longer from the buckle) if there is some left over. If your pet is squirmy, it’s best not to use scissors while they are wearing the collar – mark the spot for cutting, take off the collar, cut off the excess and then put it back on your cat again.
