Got it yesterday from Vetsupply and applied it on my two kitties immediately. Much relieved they are from those nasty bites.

Activyl Flea Treatment for Cats

Activyl is an advanced flea control formula for cats. The monthly spot-on is highly effective in killing adult fleas. The topical solution works rapidly to start killing fleas within hours of application. This novel formula breaks the flea cycle by destroying flea eggs and flea larvae in the environment not just the fleas on your cat. Thus, it prevents re-infestation and protects cats from heavy flea infestations. Activyl is safe to use in cats and kittens from 8 weeks of age.

How does it work?

Activyl works effectively by using the method known as bioactivation. Activyl is spread through the oils in your cat’s skin and coat. When a flea lands on your cat, the flea contacts the Activyl. The active ingredient indoxacarb present in the product is fully activated by using the flea’s own enzymes. When it reaches its full active form, the flea is paralysed and is unable to feed on the pet. This is called bio-activation – a new technique in controlling fleas. Activyl is waterproof and dries rapidly, but it is recommended that treated pets are not bathed or allowed to swim within 48 hours of application with Activyl.

  • Weigh your cat before starting the treatment.
  • Hold applicator in upright position away from your face and snap tip open by bending it and folding it back on itself.
  • Part the hair and place applicator tip against the skin at the base of skull. Applying the product at the base of the skull will help prevent the cat from licking the product.
  • Squeeze applicator firmly applying entire contents directly to skin. Do not allow product to run off. Do not have contact with treated area until completely dry.
  • It is recommended to reapply every 30 days or as needed.
  • Do not treat cat again with Activyl within a month.
  • When application is complete, follow the Container Handling instructions written on the pack.

Kills fleas and prevents infestation

This product is highly effective. I have two kitties and both of them got fleas simultaneously. But after treating them with Activyl, the infestation has finally gone and it's been three months since then and both of them are healthy.

Best for heavy flea infestation

I used it on my dog a couple of months back. It is a very effective product and you don't need to worry about the safety as well.

Works great

Our is badly hit by fleas and it seems no more medications working. I shifted to activyl for my two cats and happy that it actually worked with no more flea infestation to worry about.
