Hi everyone, I'm writing to see if anyone else has seen this/ thinks I should be concerned: I've recently noticed what look like calluses on Valentine's feet. It's just the hind feet, the first and last toe of both of them. I was clipping his nails today and saw that one has actually developed an outgrowth, like a little nail. It doesn't seem to bother him at all, but it is WEIRD! A dozen years of keeping ferrets and I've never seen this before! All three ferrets (not sure if I've officially introduced Asa yet) are on the same linoleum flooring with blankets on it, and Vally's the only one with callused toes. This has happened maybe within the past month or so. He's not dealing with wire flooring or anything, so I'm kind of at a loss. Any ideas? Thanks! Rachel, Valentine, Eddie, and Asa [Posted in FML 6905]
