Seresto Collar for Cats: 8 Months Flea & Tick Protection

Seresto Collar is a comfortable and hassle-free way to protect your cat against fleas and ticks. This long-lasting flea collar features a unique polymer matrix technology to provide 8 months of continuous parasite prevention.

This collar is widely recommended by veterinarians and is suitable for cats and kittens from 10 weeks of age. This easy-to-wear collar is odorless and non-greasy and may work as an alternative to oral treatments for fussy felines that resist taking anything new by mouth.

This collar is designed with a breakaway release mechanism. So in the unlikely event of your cat getting trapped, their own strength is usually sufficient to widen the collar and allow for quick release.

Why choose the Seresto Cat Collar?

Seresto flea and tick collar for cats extends 2-way protection to your cat against fleas and ticks. It:

  • Repels and kills fleas before they lay eggs, including fleas that may transmit bartonellosis, tapeworm infections, feline infectious anemia, and rickettsiosis
  • Kills fleas, which may cause Flea Allergy Dermatitis (FAD) or Flea Bite Hypersensitivity (FBH)
  • Repels and kills ticks for 8 months, including deer ticks, American dog ticks, brown dog ticks, and lone star ticks
  • Repels and kills ticks that may transmit Lyme disease, anaplasmosis, Rocky Mountain spotted fever, cytauxzoonosis, ehrlichiosis, and babesiosis

Seresto Cat Collar: Fast-acting flea treatment

Seresto Collar kills fleas and ticks through contact, so parasites do not have to bite your cat to get killed. The active ingredients flumethrin and imidacloprid are stored in the collar and are slowly released over 8 months with the help of the polymer matrix technology. These ingredients spread from the site of direct contact over your cat’s skin surface. The combination of these ingredients works effectively against fleas and ticks throughout the coverage duration.

After 24 hours of application, new fleas are killed within 2 hours. New ticks are repelled and/or killed as quickly as 6 hours after the initial 48 hours of application.

Ingredients

Imidacloprid, flumethrin
