I have a humping ferret. He had one adrenal removed also. I was told he probably was humping because his other adrenal was affected. I understand this is not uncommon. I am not removing the other. When he gets too annoying, I just pick him off of his true love of the moment, and play with him until he forgets what he was doing. Or I put him in the big comfy cage. Mine is not urinating or sprinkling all over, having trouble urinating, or losing any fur. I would see the vet if he were. Lisette [Posted in FML issue 3014]
