We have noticed a couple of fleas on our sphynx. We also have a persian whom we treat with frontline (which Im starting to think is worthless after 24 hours!) . I know that we cannot treat our sphynx with topical treatment but what can I use? They dont appear to be biting or even hanging out for long. We are having the house treated, but dont want our babies to suffer in the mean time. Any advice is appreciated!
