Hi! I have tried the deli cup. Left him in there for about 5 hours or so. He just zips around the deli until I let him out. Last time he pooed in there, a lot of fun to clean up

He's in a 10 gallon. 85 degrees on the hot side, 70 on the cool side. He's in aspen substrate about 3-4 inches deep. He has a hide and some plants but he doesn't really use them, just burrows. He has a water dish on the cool side. He definitely drinks because its always low in a few days and sometimes I see him soaking in there.
