Best Overall: Seresto 8 Month Flea & Tick Prevention Collar for Cats & Kittens

Seresto 8 Month Flea & Tick Prevention Collar for Cats & Kittens

Part of having a pet is dealing with unwanted pests. To banish unwanted critters like fleas, make sure that your cat wears a flea collar. Most collars are designed to kill fleas on contact, minus the irritation, so you don't end up dealing with an infestation or the bothersome itching associated with these bugs.

For a reliable and effective collar, we recommend Seresto’s 8-Month Flea & Tick Prevention Collar, which is the gold standard of flea collars. While it’s at the higher end of the price spectrum, it kills fleas and ticks on contact without requiring them to bite your cat first. The collar itself is non-greasy and odorless and contains two active ingredients: imidacloprid (which controls flea infestations) and flumethrin (which repels ticks, larvae, and nymphs). Together, they provide eight months of protection against all the pests in your home or yard. 

“Seresto is the besto,” one Chewy customer writes, and they’re not the only one singing this product’s praises. This is a flea collar that works exceptionally well, buyers say, even in comparison to modern topical treatments. It won’t irritate your cat’s neck, and most buyers report that they’ve discovered dead fleas within a couple of days of use.

Best Natural: TropiClean Natural Flea & Tick Cat Collar

Made from 100 percent natural oils, the TropiClean Natural Flea & Tick Cat Collar is chemical-free and safe for your pet. It kills fleas on contact with no biting required and produces visible results within 24 hours. It’s waterproof so you don’t have to worry about removing the collar during bath time, and each collar works for four months. The two active ingredients, cedarwood and peppermint oil, are known to repel fleas and kill them on contact. This breakaway collar will snap under the strength of a five-pound cat, helping to keep your cat safe is he or she gets stuck. 

The TropiClean collar can be used on cats over four months old. Because it’s made with essential oils, it’s safe around children and other pets.

Best Collar Tag: Only Natural Pet Easy Defense Flea & Tick Tag for Dogs and Cats


The Only Natural Pet EasyDefense Collar Tag is designed to attach to your cat’s current collar and help protect her from fleas and ticks for up to 12 months. It’s chemical and pesticide-free and uses silicon dioxide particles to fight off fleas. Each tag is coded with frequencies that irritate fleas and ticks but are totally safe for your pet. It starts working after three weeks, once it has synced with your cat’s unique biological frequency. It works for flea prevention, but will not eliminate a current infestation. 

Owners say the Only Natural Pet EasyDefense Collar is a great choice for anyone looking for a safe, chemical-free alternative to standard flea preventatives. Some reviewers say it takes a little over a month to start working, but once it does it keeps ticks and fleas at bay for a full year.

Best for Kittens: Arava - Dead Sea Pet Spa Arava Flea & Tick Prevention Collar

The Arava Flea & Tick Prevention Collar is made from all-natural oils, so it’s safe for cats and kittens of all ages. It provides up to six months of flea protection and is naturally waterproof. In terms of its formulation, it contains 11 natural botanicals such as geranium, peppermint, and cinnamon. Each collar is 13.8 inches and can be adjusted to fit your cat’s neck. Many owners recommend waiting one to three days after opening to put the Arava Collar on a cat because it has a fairly strong scent at first. 

Most Amazon users rate Arava over four stars, stating that they love that it protects against fleas and ticks without harmful chemicals. It’s easy to put on and fit to even the smallest neck and while some cats may be bothered by the scent, it quickly fades away.

Best Long Lasting: MASOLD Flea Collar for Cats

Seresto 8 Month Flea & Tick Prevention Collar for Cats & Kittens

While most flea collars offer around eight months of protection, the MASOLD Flea Collar for Cats will ward off pests for an entire year. Using non-toxic ingredients, this collar kills and repels fleas, ticks, lice, eggs, and larvae. It fits cats of all sizes and is water-resistant, so there’s no need to take it off during a bath or if your kitty goes out to play on a rainy day. 

If you’re looking for a “set and forget” flea collar (and don’t want to have to remember to change it every so often), this one from MASOLD is a great choice. And since the ingredients are non-harmful to cats, you don’t need to worry about your pet licking or biting it. Just make sure they’re over 10 weeks old before you start them on it. 

Best Multipack: Bayer Animal Health Seresto Flea & Tick Collar for Cats

Don’t want to rush to the store every time your cat needs a new flea collar? Good news: this flea collar from Bayer is sold in packs of three, giving you over a year of continuous pest protection in a single purchase. Each collar included in the pack offers eight months of coverage and is non-greasy and odorless. The ingredients are safe for cats (they’re the same ones found in our “best overall” pick) and kill fleas, ticks, and flea larvae. The collar replenishes the skin and coat with a low concentration of the preventative, so it remains effective throughout its period of wear.

While the Bayer Animal Health Seresto Flea & Tick Collar is on the expensive side, customers reported that it’s worth spending the extra money. These collars are highly effective, even if you own a cat that spends significant time outdoors. If you’re looking to provide years of flea and tick protection in a single purchase, this three-pack of Seresto flea collars is a great option.
