Seresto is a breakthrough product, offering the longest flea protection for cats available on the market in a safe collar form.

Seresto provides 8 months continuous protection from fleas. Seresto works to treat and prevent flea infestations by killing adult fleas on your cat and flea larvae in their surroundings. Seresto also treats and controls Flea Allergy Dermatitis. Seresto harnesses innovative technology, which allows for controlled-release of active ingredients (actives) into the lipid layer of your cat's skin and hair, meaning consistent concentrations of actives for the full 8 months.

The actives are integrated into Seresto's innovative polymer matrix. Low doses of these actives are released from the matrix overtime and migrate into the lipid (fatty/oily) layer of your pet's skin and hair. Actives are not absorbed through the skin, but remain within the naturally water-resistant, lipid layer of the skin and hair. The actives in the skin and hair of your cat kill fleas on contact, so they don't need to bite to be killed, unlike with oral tablets where every flea absolutely must bite and take a blood meal. The hair and dead skin your cat sheds naturally each day contain small amounts of actives, enough to kill flea larvae that may live in your cat's surroundings, your home.

Seresto treats and controls Flea Allergy Dermatitis and reduces the spread of flea-borne diseases such as cat scratch disease (Bartonellosis) and the flea tapeworm. The collar is designed with a safety-closure mechanism, allowing for a quick release in the unlikely event of your cat getting stuck. Seresto is odourless and safe for kittens from 10 weeks of age.
