I've been feeding him just peanuts ,raisins and broccoli before stumbling apon this forum yesterday. I think it may just be a Calcium deficiency but due to it being really rough (in staid of soft like the rest of his body)so that also leads me to believe he has mange but only in his tail. I first found him outside near my pond crawling up my pants leg and I've had him for a fue months now. His tail having not fluffed out at all is fritening me quite abit. So if anyone has any information on how to help my little fuzz ball he and I would gratefulty appreciate it
