It appears his oil gland is inflamed. It was very dirty down there, like allot of ashes. They dust in the fire pit. He couldn't walk so I checked him out and cleaned him up. He is not sick, but seems to be in much pain when I touch his oil gland. Still can't walk. I've been putting warm compresses on it. Of course he is isolated and I also have been giving him extra vitiman A. Thats all the info I can find. Has ANYONE else dealt with anything like this????
