I really can't get a good picture. His skin is really tight (you can see the edges of his skull), you can see bumps on his back which kinda look like bone, and other areas have faint red dogs like you see when you get a really bad skin burn. His sores (ulcers?) on his belly haven't been healing either.

This is all chrytid, yeah? Slow onset, redding of belly, shedding of skin, formation of growths, watery abcesses, and lots of thinness. I think I'm gonna put him back on the chrytid mess. Obviously doing nothing isn't working, and the antibiotics didn't work before even though I basically completed them.

For what it's worth, his poo was runny a few weeks ago before it turned gray. Not liquidy, but not like super solid.
