What a hard question, I have a ferrel in my office, he has been here along time, i guess 8 months, anyways I tried to do the tame him and make him love me thing. So at first he did well, so I thought Id let him out and see what happened. Here it is 4 months later and I finally caught him again 2 days ago. So he will be nuetered this sunday, and given a rabies shot. I guess I need to test him. But back to your question, he shows no sign of being sick, and he has been here along time, i guess he would live his life out here, as there would be no way I could put him down. But if anyone is interested, I really want to find him a home here in the DFW texas area, where he can go back outside and live in the country and be a barn cat. Just needs someone to feed him. anyone interested?
