I'm not a vet. Seven isn't really that old, I've had them lie to ten, I've heard of eleven and twelve year olds. Your ferrets might be losing control of his baldder due to a partial blockage--very common in older males. Generally there is an adrenal tumor that's involving the prostate which then blocks the urethra. It's also possible that he's had some seizures as a result of the insulinoma that have caused brain damage. My advice is to cage him and clean the cage as needed. Give him plenty of free time on a non carpeted floor. Another possibility is to get two Marshall's Ferret Playpens and hook them together, Put plastic carpet protectors down, and throw some towels over that. Easy to clean, plenty of room. My girls live full time in that setup, minus the carpet protectors--I've got tile floors. I let them out for a couple hours each morning and night. But more importantly is to have the vet rule out a blockage--that can be fatal if not treated. Anne [Posted in FML issue 5197]
