I"m trying to attach a pic. Any help would be appreciated. Mac has a swollen hind foot and a little discoloration on the top of it. I think he got it caught in his cage when he was jumping around. I couldn't find any good pictures of what gout looks like so I wanted opinion about it. It isn't from shedding, and he still uses it fine. He has a big cage, good diet and lighting. any help appreciated.
