  • Seresto® collar for cats is engineered for 8 months of continuous protection.
Seresto eight-month flea & tick collar for cats

Truly unique collar technology for your cat.

  • Seresto® is a unique polymer matrix flea & tick 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 your cat'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. 

     

Seresto® means 8 months of
effective, convenient flea and tick prevention.
