Product Description

Activyl for Cats

What do our customers say?

"Fantastic!  Activyl is the absolute best flea treatment for our cats that we have ever used! We have used other popular name brands in the past but none have been as successful as Activyl. We discovered Activyl almost a year ago during our search for a better product for treating fleas on our cats. Sadly, we have recently found that our local pet supply stores have stopped carrying it. So, on my quest to find how I could purchase it I luckily found Countryside Pet Supply and could not be happier! CPS has the best price available and shipping was quick as I received my order earlier than expected! I would definitely recommend this product and CPS to anyone looking for reliable products from a reliable company! Thanks so much for the fantastic experience!"

"Frontline and Advantage did not work any longer for my two cats. With Activyl the flea does not have to bite for it to be effective so wonderful for my flea sensitive cat. No more sores from flea bites.

Activyl is a highly effective spot-on flea control treatment featuring indoxacarb and a mode of action that uses enzymes inside the flea to activate the serious flea-killing power. Both pets and people want a flea treatment that's really effective at killing fleas and preventing infestation, but how it works matters, especially regarding the impact to your pet and home.

Activyl ensures that your furry family member gets the best care possible. It's also quick-drying, fragrance-free, waterproof and remains effective even after bathing.

Activyl breaks the flea life cycle

Unlike some flea treatments, Activyl doesn't just kill adult fleas, it also stops flea eggs and larvae from developing. Breaking the flea life cycle is important, so your pet is not re-infested by new fleas developing from flea eggs and larvae in your own home environment.

Activyl for Cats is the flea treatment just for cats. Both products kill adult fleas and also break the flea life cycle, so you're much more likely to solve your pet's problem for good.


Step 1: Application

Activyl spreads through your pet's skin and coat.

Step 2: Contact and Ingestion

When a flea lands, it takes up Activyl (no bite required).

Step 3: Activation

Enzymes inside the flea change Activyl into its fully active form.

Step 4: Flea-Free

The flea is soon unable to feed, becomes paralyzed and dies.

NOTE: At the beginning of Phase 4, fleas become disoriented and move in the coat of your pet, which makes them more visible to you. These fleas stop feeding, followed closely by paralysis and death.

Activyl for Cats - 6 Month Supply


Very pleased

Actively for cats

I highly recommend Activyl for cats that are outside. It's the only waterproof flea product on the market. I comb my outdoor rescue cats and when I use Activyl there is maybe 1 flea a week on my cat. When I use Advantage, the fleas never go away. Delivery was fast, product was packed in a strong shipping box!


Started out fine. One cat had severe reaction. Two weeks later seems to be losing affect


It works - No more scratching - Until next month.
