Hello! I have 1.5 year old male Argentine B&W. I acquired him on the 30th of November so I haven’t had him for too long. He’s ate great (I feed him a meatball with zucchini in it every other day and give him a f/t hopper mouse once a week) and loves to be handled. About 5 days ago, he rejected his food. So I tried the next day and he didn’t want it. I was assuming that we was going to take a long nap or begin brumating because he went from being active to sleeping all day so I stopped feeding him and I gave him a warm bath so that he wouldn’t be sitting on his meal. Today I noticed that the rear end of his body was started to get bloated and had a lump. When I touch it, it feels rather firm and not too soft or anything. However, when I touch his belly, it feels really soft and like it’s full of air. Nothing about his body looks wrong accept for his rear end. No cloudy eyes or awoken joints or anything. He drinks out of his bowl every day. Please let me know what to do, I’m starting to get rather nervous about the situation and don’t know the problem or solution. Thanks!
