Discover an odorless, non-greasy flea collar that kills and repels fleas and ticks through contact.

How It Works

The Seresto cat flea collar works with a unique polymer matrix of two active ingredients, which spread from the site of direct contact over the skin surface of your cat from head to toe, even the tail.

The innovative Sustained Release Technology of Seresto for Cats collar kills and repels fleas and ticks for eight continuous months.
