How does Seresto for Cats work?

How does Seresto for Cats work?
Active Ingredients: Seresto’s innovative polymer matrix stores two active ingredients, imidacloprid and flumethrin, within the collar.
Innovative collar technology: Once fitted to your cat, the active ingredients migrate from the collar and spread through the fatty/oily layer of your cat’s skin and hair coat, where they work on contact to kill fleas and ticks.
Long lasting protection: The active ingredients continue to migrate in low doses from the collar to your cat, as needed, to provide continuous protection against fleas and ticks for 8 months.

Steps on how to apply Seresto™
1.
Remove the Seresto™ collar from its protective pouch and unroll, ensuring that no plastic connectors remain attached to the inside surface of the collar.

2.
Put the collar around your cat’s neck and insert the loose end through the two loops.

3.
Adjust the collar around the cat’s neck without it being too tight or too loose. It should be possible to fit two fingers comfortably between the collar and the neck.

4.
Cut off any extra collar length, leaving about 2 cm of the loose end beyond the second loop. Check collar periodically and adjust the fit as necessary. For kittens, leave additional length to allow for adjustment of the collar as they grow.
