Best Cat Flea Collars

PetGuide logo

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.

In addition to flea products that are designed to be taken orally or applied topically, there are also flea collars 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.

But First, A Note About Flea Collar Safety

Keep in mind that 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.

For example, 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.

  1. 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, 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, 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.

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.
