You're actually seeing him, we're not- so I'd say "trust your gut" on this. He has a separate "warm" hide that he's not using? Either find something else that's better suited, or another way to make his warm hide more cozy- ie. put something inside it to make it smaller & see if that helps him want to use it. (I've never used ANY hides that have a bottom- a "floor"- in them- all mine are open bottom because I use UTH.)
