Yesterday, I got an approximately 4 inch P. murinus from my local pet shop. It didn't come out of the cup that it was in for some time, but at soon as it did, it ran extremely fast through the enclosure up the walls and almost escaped (I shut the screen fast). It walked around the sides for the longest time, looked very cool. But now it enclosed itself in the hideout that I gave it and it put substrate all over it perfectly so that it cannot be seen. I was informed that it molted two weeks ago and this particular one has a "nasty" temperament. It's abdomen is of a good size so it's most likely eaten recently. I know this species is said to be semi arboreal, but what else should I expect from it? I am worried about the fact that it has entirely covered it's retreat and it staying in there. If it stays in there too much longer, should I encover it? If it stays in there how am I supposed to feed it? Any advice? I think I read in another threat that Mr. T has a P. murinus; any advice from you?
