State-of-the-art flea and tick protection for your cat.
With its innovative delivery system, Bayer's Seresto collar offers a breakthrough in flea and tick protection for cats. A single collar protects for 8 months, combining the performance of a topical with the convenience of an easy-to-use collar that is non-greasy and odorless.
Seresto is a unique polymer matrix collar that provides a continuous supply of two active ingredients, imidacloprid and flumethrin, for effective 8-month protection against fleas and ticks. That's one convenient collar instead of 8 expensive monthly treatments. The active ingredients are stored within the collar. They are released in low concentrations and are distributed over your dog's hair and skin surface for 8 months. As active ingredients wear off over time, Seresto continuously replenishes the skin and coat with a new supply of active ingredients. Fleas and ticks are killed through contact with the active ingredients — no biting required. Quickly kills fleas within 24 hours of initial application. Reinfesting fleas are killed within 2 hours. Prevents tick infestations within 48 hours after application.
This collar features a release mechanism which, in the unlikely event of a pet becoming trapped, the pet's own strength is sufficient to allow for a quick release. The collar is also water-resistant and remains effective following monthly bathing, occasional swimming (if swimming occurs more often than once a month, the duration is reduced to five months) or after exposure to rain or sunshine.
