Can I just do a fecal float in sugar solution like with a dog or a cat? I work at a veterinary office so it wouldn't be hard for me to do that, but no one there is a reptile specialist. . . just dog/cat stuff.

I plan on getting a lot of stuff for him to feel comfortable in the cage and I plan on making it a front door opening versus top lid if I make it myself.

I will try a small rat next time, I just don't know if he is that thick around. I will see if I can get more pictures of him when he is more calm.
