I don’t advocate giving cats baths; it’s usually unnecessary. Percy, however, is 1/2 Persian with very long hair and he became infested with fleas early, early in the flea season. I thought the Frontline flea treatment would work better if we killed the live fleas first. I’ve flea bathed probably a 100 or more cats in my years of animal rescue and cat guardianship, but, truly, Percy was the worst behaved one of them all! He sure can give the hate looks, can’t he!
