So my new adopted guy, Bahamut, is still going through treatments for his sickness (RI/Ecoli) and I got a new heating pad yesterday since the other one was a tad small. I have had a cardboard box for his hide since I got him, which he has been using no problem. Now, I put the new pad on the thermostat and get it all nice and taped down. I switch to using paper towels instead of Cypress for the time being, put his hide box back in, and now he wants nothing to do with it. He lays on top a little but did not go inside at all except to look around. The only thing I could think that would be the problem is that the box can move since it's on paper towels, so it doesn't feel as secure to him. I put some regular towels on either side to stop it from moving, but he's still just hanging out on the cold side or is constantly moving around. Any ideas? He is in a 20g long. Temp above heating pad is 92-94 and the cool side is 83-85. I'm keeping temps high and humidity on the lower end while dealing with his RI. Any ideas why all of a sudden he doesn't like his hide?
