My friends cat has these little brown bugs crawling around her kitten. They tend to travel in groups, moving from place to place, but are generally on the back of his head. They are about the size of aphids and we can't figure out what they are. They don't seem to be bothering him, but if anyone knows what they are and/or what to do to get rid of them, it would be awesome.

Also, flea bath and flea collars have not been working, and we're worried that the bugs may travel to the other cats in the house.
