Using a flea collar is the easiest and surest way to keep parasites away from your cat. Not only will it kill biting pests but it will also prevent an infestation in your cat’s fur and in your home. While being as effective as other solutions, cat flea collars are more affordable and safer for your pets. Fleas are not just an annoyance. These dangerous insects can cause a cat flu, dermatitis, anemia, and other diseases in cats. That is why it is highly important to choose the right collar for your furry friend.

Let’s start with the fact that there are two types of cat flea collars. The first and most effective one is an insecticide-impregnated flea collar. Saturated with an insecticide, the collar releases the chemical as it rubs up against the animal’s body. This chemical is then absorbed into and spread through the cat’s skin.

Depending on the type of ingredient, parasites will either be killed on contact or will need to bite the skin to be affected by the insecticide. The latter makes a flea collar less safe for cats, which is why we advise options that work on contact, such as the Bayer Seresto Flea and Tick Collar for Cat.

Made by a trustworthy brand and recommended by veterinarians, this product kills fleas and ticks once they come in contact with its active ingredients. The formula is based on two insecticides that act in a different way, providing complete protection to your pet. While imidacloprid kills adult fleas and their larvae, flumethrin targets ticks, killing and repelling all their stages of life.

This cat collar is amazingly long-lasting and provides 8-month protection against fleas and ticks. With clinically proven efficacy, this product eliminates fleas within a day of application and keeps your cat tick-free for two days. In addition to awesome results, this non-greasy and odorless collar is comfortable for cats to wear.

For budget buyers, there are cat flea collars for under $50, such as the Flea and Tick Collar for Cats – Natural Prevention Treatment. Based on essential oils, they can only repel insects, whereas the Bayer Seresto kills them as well.

That said, the effectiveness of natural ingredients is questionable since they are not as strong as chemicals and evaporate quickly. More importantly, natural does not automatically mean safe. According to the study carried out by the University of Illinois College of Veterinary Medicine, 92% of the test animals experienced side effects after exposure, including vomiting, seizures, and agitation. This is particularly true for cats because of their grooming behavior.

The second type of cat flea collars uses ultrasonic technology to repel insects. Manufacturers state that ultra-high frequencies disorient fleas, however, there is no sufficient scientific data to prove these claims. Many field and laboratory tests involving ultrasonic devices have shown that they are not effective against fleas. Nevertheless, if your cat is sensitive to insecticides, you may give a try to a product like the Max & Molly Zerobugs Ultrasonic Flea & Tick Prevention Collar Tag.

What Alternatives to Cat Flea Collars Are There?

If you have to deal with tough flea infestations, you may use topical flea control products. This is also the easiest form of flea control for cats. You will only need to apply the solution to one spot on the skin one time a month.

Once applied, this spot-on solution spreads across your cat’s body, without leaving any residue. This kind of treatment is more effective than flea collars but is more likely to cause adverse effects in animals. For this reason, it is recommended that you consult a veterinarian before starting your cat treatment.

The most popular and best-selling product in this category is the Advantage II Flea Prevention and Treatment for Large Cats. Designed for cats that weigh 9 pounds and over, the Advantage cat flea drops kill these insects on contact, protecting your cat for up to one month. The next day after application, the solution becomes waterproof. The formula is based on the blend of two powerful ingredients, imidacloprid and pyriproxyfen.

Another option is the Frontline Plus Flea and Tick Treatment for Cats. The solution can be used on both adult cats and kittens 8 weeks and older. It effectively stops flea infestation with two ingredients: fipronil and (S)-methoprene, which have absolutely different modes of action. Fipronil targets adult fleas, killing them by disrupting their nervous system. One of the advantages of fipronil is that there is no significant resistance among fleas to this insecticide. The other active ingredient, (S)-methoprene, controls flea eggs and larvae. This chemical acts as an insect growth regulator, preventing larvae from reaching maturity. Note that it is insect growth regulators that are considered by scientists to be the most efficient long-term insect control method.
