I have noticed that my ten week old kitten has been having these tiny little yellowish eggs(I think so) coming from his anus. I have been finding them on his blanket and chair that he lays on. At first they appear to be like soft, but afterwards they get hard. They are so tiny, I barely see them. But lately I have noticed more and more. Are they fleas eggs and are they supposed to come out of his anus? Is a ten week old, old enough for a flea bath?
