Product made my dog itch constantly for 24hrs, with no relief at all only agrivated the fleas on her, now I need to buy another product to try and give her some relief, complete waste if time and my money

I have 2 older cats (13 and 14yo) and am very careful what I give them. One cat is allergic to fleas so when he does get them I need to act fast. Capstar is really effective at providing instant relief and doesn't seem to have any side effects, I just wish it lasted longer as both cats really hate the spot on treatments and unless things are desperate I try to avoid giving them.

Easier to use than the vials - just pop it in their mouth and it's done. No side effects.

We use the product to kill off the fleas on the cat prior to using revolution on a monthly basis. Cat stops scratching within the hour after taking the tablet. Best product on the market, recommended by the vet.

I only use this product during the summer months in conjunction with Sentinel and have never found a flea on either of my dogs.
