Your getting better! Being picky - Both hides should be the same thing. I use kitty litter boxes. But I have a big boy. You don't want to give him the option of different hides because he might like one more then the other because it is more confined and he might feel more comfortable in one rather then the other. But he might be cold and want to move to the other side but he wont because... he likes the hide on that side better then the other!
Keep it up!
