My 5 month old kitten has long black bugs on her that we find occasionally, usually pull them off of her face. I haven't gotten a great look at them because they are fast and usually squirm away before we can get them, but I think they're as long as a grain of rice, thin, black and they burrow away. She has been treated with Revolution for the past 2 months, once just a week ago. She doesn't have any flea dust anywhere on her body and she doesn't really itch anything. Has anyone else experienced this?? Revolution treats for fleas, ticks, mites, and heart worms and is supposedly the best stuff for kittens. Please help!!!
