I have a 4-5 yo MF male ferret who started loosing hair on his mid/lower back. It started very light and wasn't real noticable at first, but then started falling out rapidally. I was all most positive he was adrenal and started saving up some money to pay for his vet bills I assumed he'd be having in the near future. Well, about 2-3 weeks after loosing the hair completely off his back area [it leads from the bottom of his shoulders down to the base of his tail-no hair loss on the tail, feet, belly, head and neck], he has started rapidly growing the hair back. It's very short thick grey hair, with a few scattered black guard hairs growing in right now-but it's definally growing back in. He has absolutly no bald spots now. He lost absolutly no weight, remained fully active and playful through this whole time. I'm thinking it's possible he's still adrenal, but am very unsure if hair grows back after falling out? Is it possible he's adrenal or are there any other explanations? He's still going to the vet, but I really wanted to hear other ferret owners experiences and opinions. Dooky [Posted in FML issue 3273]
