ANNOUNCER: Seresto® protects your cat against fleas and ticks for eight months. It offers the performance you expect from topicals, but with the non-greasy, easy-to-use convenience of a collar.

With its sustained release technology, it offers dependable flea and tick control for cats.

Seresto® is easy to use and takes just moments to apply to your cat.

Remove the collar from its protective bag directly prior to use. Unroll it and remove the small plastic connectors from inside the collar, ensuring no remnants remain.

Simply insert the end of the collar through the buckle and loop. Adjust the collar around the animal’s neck until it fits comfortably on your cat. Two fingers should fit between the collar and neck to ensure it is not too tight. Any excess length of the collar beyond an inch past the loop should be cut off. Also, make sure the collar cannot be pulled over the head. Check periodically and adjust fit if necessary, especially if you have a kitten that is rapidly growing.

Seresto® comes with three optional reflector clips that can be attached to the collar to help keep your cat visible at night. The reflector clips should be evenly distributed on the non-overlapping part of the collar.

After Seresto® has been applied, it provides continuous protection against fleas and ticks for eight months.

Seresto®. The performance you expect from a topical, in a convenient, easy-to-use collar.
