Seresto® for cats kills and repels fleas and ticks for 8 months in an easy-to-use, odorless, non-greasy collar. You'll both appreciate 8 months of continuous flea and tick protection. Cats are independent by nature, but they still need your help with flea and tick protection. Seresto® for cats is designed to be a convenient way for you to help protect your cat from fleas and ticks that can cause bites. Our innovative Sustained Release Technology provides protection from fleas and ticks for 8 continuous months in each non-greasy collar. That's one easy-to-use collar instead of 8 monthly treatments. Truly unique technology for your cat. Seresto® is a unique polymer matrix collar that offers a continuous supply of two active ingredients: imidacloprid and flumethrin for effective 8-month protection against fleas and ticks. That's one convenient, non-greasy, odorless flea and tick collar instead of 8 monthly treatments. The active ingredients are stored within the collar. They are released in low concentrations and are distributed over the pet's hair and skin surface for 8 months. As active ingredients wear off over time, the Seresto® flea collar for cats continuously replenishes the skin and hair coat with a new supply of active ingredients. Fleas and ticks are killed through contact with the active ingredients - no biting required. For 8 month prevention and treatment of fleas and ticks on cats and kittens 10 weeks of age and older: REPELS AND kills fleas and ticks Repels and kills ticks for 8 months, including Deer ticks (vector of Lyme disease and anaplasmosis), American dog ticks (vector of Rocky Mountain spotted fever, cytauxzoonosis and ehrlichiosis), brown dog ticks (vector of ehlichiosis, anaplasmosis, babesiosis, and Rocky Mountain spotted fecer), and Lone Starticks (vector of cytauxzoonosis and ehrlichiosis).
