Why do I still have fleas??
All four of my girls have Frontline Plus on them and I'm constantly going over them with a flea comb. I've sprayed my furniture and every nook and cranny with Zodiac FleaTrol and then I shampooed my carpet with Enforcer Flea Spray for Homes. So why on earth are my cats still scratching and why do I still get a ton of fleas off of them with a flea comb?? Only one of them is an inside/outside cat and the other three are inside all the time so whats going on? The flea sprays are supposed to kill fleas for seven months. Shouldn't the Frontline have killed all the fleas on my cats within 18 hours? Any ideas?
