I did a search for "poop" on this site and wanted to mention it does NOT look like this one:

The poo substance didn't have any clear parts. Just a poo goop, all same texture and color. Also I do want to mention it smelled bad... I have a good sense of smell but our little Japanese rat snake's poop doesn't usually smell much, if at all. The amount of poo was like, 2-3 square inches or so.

Because each specific RAL test is $20, I think I will just do the crypto panel at this time, since I was planning on this anyway. Because there are so many other factors like him being shipped, stressed, and the fact that I don't know what he used to be eating, I'm going to monitor it for now.

Unfortunately, my exotic vet insists on any poop sample being less than 1 hour old in order to do any sort of testing whatsoever. I might take it in to another vet if I get another weird poop (might do this anyway, since I can't really guarantee I'll see him make the poo and then be able to go to the vet at that moment).

Any other opinions on the poo are welcome, though! I will post a photo if it happens again.
