I let him soak in warm water a little over 24 hours ago, but the purpose served well because he hadn't had a bath in a long time. But I got home tonight and he let out a poop, so I'm glad he did. My only concern now is that it doesn't look like it's big enough that it came from two medium rats. With that being said, I've never observed the quantity of poop before so it's probably just normal.
What do you guys think?
Edit: And before the police post, no he doesn't lay in the open, I moved his cave to take a picture. You can see the indents of where the cave was and his body shape.
