Oh, I didn't know you sent that link for me to compare the appearance. No, it didn't look anything like that. I did describe it in the initial post. I think I'm mostly concerned about the fact that it was stinky rather than the texture, but yeah the color and consistency was the same throughout, and was all just this stretchy (not like sticky or tacky, but like I said, like an egg white). There was a separate urate portion, I think (honestly I was just distracted so much by the weird poo but I'm 80% sure there was a urate) He has been in his "humid" hide all day so far. I raised the thermostat just a tad so the surface temp of the paper towels stay around 85 over the heated part. If he makes another poo before I feed him next week, I'll be sure to bring it in. My other vet said they could do a float for me and it could be a few hours old if I refrigerate it.
The suboc book by Dusty Rhoads said to check for nematodes, but at least this vet said they didn't know how to test for that (said they could maybe send it in, but I haven't heard back from them). I am not sure how much of a concern those are, or if you or anyone else here has any experience with nematodes.
