"What does it mean when ferrets are asleep and they stick their tongues out and just leave them there? Is this a ferret's way of cooling off?" I think it just means they forgot to pull in their tongue! I've noticed that my guys do this less as they've gotten older, and maybe the smarter ones do it less. Temperature doesn't seem to matter. If you poke their tongue and they pull it in without really waking up, they'll leave it in. It's still pretty cute. Happy Ferreting! Dennis [Posted in FML issue 1291]
