Used this on our 6 month old kittens a couple of months ago and while they do seem to have stayed worm free (they weren't showing signs to begin with so I can't comment on how well it kills worms), the product really seemed to aggravate them both and they were doing all they could to lick the spot where I applied it (the usual back of the neck) for the rest of the day. No matter how well I try to apply spot ons just onto their skin, the liquid does spread into the surrounding fur and I was worried as they got to some of it and licked it, although they had no ill effects from it. We also use a spot on flea treatment which they forget about pretty quickly, but something in this product seemed to irritate them. I would rather try tablets (with the help of Easy Pill) than use this again so that's the plan for next time!

Easy to use. Scratch free for first time after administering worm treatment.

No fuss and effective product that does not end up with me bitten or scratched :)

Brilliant product,just pop it on the back of the neck and your cat is protected for 3 months,much better than the hassle of trying to get a tablet down 👍🏼
