For the 1st 8 years of his life Arthur has slept in a triangular shaped fuzzy hut. He was sent home with it and had it since he was a baby. It literally started to disintegrate around him so I threw it out and replaced it with an identical one. He refuses to go in it. He has another “play house” (different style) that he’ll go in during the day. He won’t sleep in that either. We find him in the morning hanging on the side of his cage, next to, and touching the green hut but he still won’t go in. Sometimes he sleeps with his head resting on it. I have literally put him in it but he runs straight out the other side. Any suggestions? We feel badly for him.
