Seresto® for Cats:
Truly unique
collar technology

  • Seresto® is the leading, innovative flea and tick collar for cats that applies two active ingredients over your cat’s hair and skin surface: imidacloprid and flumethrin. This steady release of treatment is effective for 8-month protection against fleas and ticks. That's one convenient, nongreasy, odorless flea and tick collar instead of 8 monthly oral or topical treatments. Fleas and ticks are killed through contact with the active ingredients –– no biting required.

Fleas and ticks don’t stand a chance.
