I'm sorry.. P. scrofa's are very underappreciated, IMO. I have 2; and adult, and a sling. Very sweet, if a bit nervous. Not aggressive in the slightest, though. (get another one)
Mine did the same. One day it was fine, as for as I could tell, then the next it was dead. I think the substrate was too dry.
I wish I knew. I'd like to get another, but I want to know what I did wrong, so I don't kill another one..
