I have a hidey house that has a little ramp so that he can get on top. He was never able to for a couple months but he finally figured it out. But now he hardly ever gets off of it. He eats food from the hay feeder attached to the house, he sleeps there, uses the bathroom, and won’t come off to play. The only time he leaves is to drink water. Is this an actual issue and if it is, should I do something?
