Activyl Spot On Large Cat (Over 4kg)

Activyl Spot-On Solution for Large Cats is a highly effective innovation for the treatment and prevention of flea infestations in large cats weighing above 4kg.

The solution contains the active substance Indoxacarb which works using a process called bio-activation. This mode of action uses enzymes inside the flea to activate and produce an active compound that interferes with the flea’s nervous system.

Once activated, Activyl will not only kill adult fleas but also break the flea life cycle and prevent eggs developing into larvae.

Activyl Spot-On Solution for Large Cats can also be used as part of a treatment strategy for the control of Flea Allergy Dermatitis (FAD).

Each 1.03ml pipette contains 200.85mg Indoxacarb.

It is supplied in packs of 4 single use pipettes.

Nearly half the price of vets and pet shops. Great value and delivery


They are always very helpful if I've had to ring . I order tablets monthly on line and it couldn't be easier. The system is easy to use. I've been buying from them for 2 or 3 years and it saves so much money compared to vet prices.


Fantastic everytime. This was my 3rd transaction and all have been easy, quick and without trouble!
Ill continue to buy from them as with 5 cats i save loads buying from this website!


Excellent service from start to finish


Quick and easy to find the product need it and the processing time no fuss. Competitive pricing and delivery faster than expected


Can’t fault the service or goods. I always receive my cats prescription drugs within 3 days from ordering. It also saves me over half the price I would pay at my vets.
