Nikita and Merlin have shown up with the same problem in the last two days: they are losing the hair on their tail. Nikita, our albino female, is presumed to be 2 to 2 1/2 years old (guess) and Merlin is a certain 1 1/2 years old -- he is our deaf baby. My question is this: How can I tell if they have Rat Tail or are Adrenal, and if they have Rat Tail, what can I do about it? They have a few black heads on their tails, but not an over abundance. We just noticed Merlin's hair loss tonight, but Nikita's has been going on for a few days. She went from half an inch bald on Saturday to half her luxurious tail bald today, Monday. Please help.
