Seresto is an innovative, odorless and water resistant collar that offers protection against fleas and ticks in your dog and cat. The collar with a duration of action of up to 8 months continuously releases a low dose of the active substances imidacloprid and flumethrin. The dosage of the active substances of the flea collar is so low that it is safe for the health of humans and animals. The two active substances are spread over the cat's skin and fur via the collar. The collar works both repellent and killing against ticks. If ticks are already present on your cat before applying the band, it is recommended to remove them.

In addition, the collar protects against the development of flea larvae and can be used as a treatment for lice infestation (Trichodectes canis). The active substances work synergistically. Small amounts are gradually released through the microlayer on the surface of the collar. The active ingredients of the flea collar spread from this microlayer to the sebum layer of the skin and coat. Neutral oils help to spread over the entire sebum layer. The active ingredients move to the sebum layer when needed.

This process is regulated by the difference in concentration between the collar matrix and the surface of the collar, resulting in very accurate dosing. As a result, an optimally low protection dose remains present for 8 months. Seresto cat can be used in cats.
