Snickerdoodle is terribly smelly. Well, actually, it's his cage. It smells a little like vomit. His poop doesn't smell, and I sniffed him, he smells fine. It's most likely his urine, but what could cause this? No dietary changes, he's not stressed AT ALL ( he is happier than ever!!!) but his cage stinks!!!! I know what you're all going to say, it's the food or he's stressed, but that is not it. The bedding was changed three days ago. Is he sick???
