Hi Anon. I have three ferrets, two are female sables and one male albino. I agree with you on the sables being a little smarter. My albino ferret (Ruby) can't climb very high, nor run as much. He is still a sweetheart, but very mellow. When the other ferrets play, he has a hard time keeping up, and really doesn't care to always play with them. Also, my two sables will sit for a treat, he won't. I don't know if it is because he is a albino, or his age, or even him being a male. I wonder if anyone else has notice that kind of behavior? Thanks. Kimberly & Greg (Ruby, Bongo, and Giggles) [Posted in FML issue 1033]
