To: Steven and Colleen In the past I have had ferrets with sores on their backs. They weren't really orange, but they were watery, kind of crusty, and wouldn't heal. The sores must have been very itchy because the ferrets would chew and scratch at them until they would bleed. The sores turned out to be mast cell tumors, which are full of histamine and very itchy. They can be surgically removed, and this gives much relief to an uncomfortable ferret. So, you might check to see if these are mast cell tumors. They are quite common in ferrets.
