Yes, Seresto flea collars work for cats. Seresto is a flea and tick collar designed specifically for cats and dogs. It releases medication through the fur of your pet, creating a barrier that provides 8 months of protection against fleas, ticks and other parasites. The medication reaches the bloodstream when it comes into contact with the cat’s upper layer of skin oils. This helps to protect your cat from getting infected with parasites and diseases spread by fleas and ticks. In addition to providing long-lasting protection against these pest, Seresto also offers an odorless scent that your cat won’t mind wearing.

How Does A Seresto Flea Collar Work?

A Seresto flea collar is designed to keep cats and other pets safe from fleas and ticks. The active ingredients, imidacloprid and flumethrin, are slowly released when the collar makes contact with your pet’s fur.

Once released, the substances work together to repel both adult fleas and their eggs as well as controlling tick infestations. Fleas don’t have to bite your pet for it to be effective because the collar’s active agents block their biting action. Rather than having to wait for a flea larvae or egg hatch (like shampoos or other topical treatments), Seresto works immediately.

The active agents also last up to 8 months, so you won’t have to worry about re-application like traditional topical treatments. And because it’s worn around your cat’s neck rather than squirted onto their fur, you won’t have to worry about your cat licking, rubbing or grooming off the treatment.

Are Seresto Flea Collars Safe For Cats?

The short answer is that yes, Seresto flea collars are believed to be safe for cats when used as directed. They use a pesticide called imidacloprid to kill fleas and their eggs, while also releasing a fragrance that keeps new fleas away. This means that you don’t have to use something like a toxic topical or spot on treatment which could potentially harm your cat.

Many reviewers have testified that the Seresto collar works wonders on their cats’ flea infestations, with some saying they saw results within 24 hours of putting the collar on their pet.

It’s always best to double-check with your vet before using any products though, as they may have specials recommendations depending on your cat’s health and lifestyle. Additionally, it’s important to make sure that you properly measure and fit your cat’s collar according to the manufacturer’s instructions in order to avoid any discomfort.

What Are Some Alternatives To Seresto collars?

If you’re looking for an alternative to Seresto flea collars, there are plenty of options available. Some popular alternatives include topical medications, oral medications, and spot-on treatments.

Topical medications (also known as ‘spot-ons’) are liquid solutions that are applied to the back of your cat’s neck between the shoulder blades. These solutions contain active ingredients which destroy the flea eggs, larvae, and adults quickly and effectively. Topical medications have the advantage of being able to last from one month up to three months – depending on the product chosen.

Oral medications can also be used for treating cats for fleas. These pills are often small tablets that contains active ingredients which your cat will take orally (hence the name!). The medication is absorbed and distributed throughout your cat’s body where it continues to work at killing any fleas attached to them. This type of treatment also kills remaining flea eggs and larvae in the environment so they cannot become a new problem in future too!


If you’re looking for a safe, effective way to protect your cat from fleas, then using a Seresto collar is an excellent option. It’s easy to use, lasts up to 8 months, and is gentle enough for kittens and cats alike.
