I tried Hartz flea control on my indoor cat, it didn't work. I went to my vet and asked for advantage, they need to see her first. My cat is old and is traumatized by the cat box, car ride, muzzle in the vets office etc and I really don't want to put her through that again. Is there an alternative? They gave me one dose of advantage, I'm not sure that it will be enough.
One dose will last a month. You can try any other over the counter flea medication after the month is up. vetcare
