I have two ferretts//A cat came in our home for a day and left us with fleas. We allow the ferretts out for several hours every day...To roam freely..They do often go off is some place and sleep...They came down with severe fleas and I shampooed dusted and got them down to one flea in many weeks on each of them...However they are still scratching and one has lost his fur..I bought pine tar soap and that has not relived the scratching..The one that lost his fur appears to have browner than his skin eraser size ( give or take a centimeter blotches of discoloration not previously there before. How can I help my critters?
You can use a feline flea shampoo on them to help kill the fleas. A vet may need to look at them b/c they may have a flea allergy. Good luck, vetcare
