Seresto Flea & Tick Collar for Cats 8 Month Protection

Seresto offers a breakthrough in flea and tick protection for 8 months. Inside the unique polymer matrix of Seresto are two active ingredients: Imidacloprid and Flumethrin. Flumethrin works together with imidacloprid to provide dual action protection against fleas and ticks. The active ingredients spread from the site of direct contact over the skin surface of the animal. It works similarly to a monthly topical, but as the active ingredients wear off over time, a new supply is continuously replenished in low concentrations. It is also water-resistant. Collar is for 8-month prevention and treatment of ticks and fleas on cats and kittens 10 weeks of age and older.
