Seresto Flea and Tick Collar for Cats

Seresto Flea and Tick Collar for Cats is a veterinarian-recommended collar designed to provide premium flea and tick protection without the premium price tag. Easy to apply, odorless, and non-greasy, it offers 8 continuous months of protection for cats and kittens 10 weeks of age and older. The collar kills and repels fleas and ticks through contact — no biting required — and is designed with your cat’s comfort in mind, featuring a two-way release mechanism for added safety.

How It Helps

Seresto uses a patented polymer matrix technology that slowly and continuously releases its active ingredients over 8 months. These ingredients spread across your cat’s skin and coat to provide full-body protection.

It begins preventing new tick infestations within 48 hours of application. Existing fleas are killed within 24 hours, and any new fleas are killed within 2 hours after that, with ongoing protection lasting up to 8 months. By controlling fleas and ticks, Seresto helps reduce the risk of issues associated with flea- and tick-borne diseases such as tapeworm infection, feline infectious anemia, bartonellosis, rickettsiosis, including those carried by deer ticks, American dog ticks, brown dog ticks, and lone star ticks.
