    Best Overall: 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.

    If your cat seems to be showing signs of a flea problem, make sure to invest in one of these flea treatments for cats.

    Best Collar Tag: Only Natural Pet EasyDefense Flea, Tick & Mosquito Dog & Cat Collar Tag

    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 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.
