My hamster sleeps all day in his burrow and will try to bite me if I attempt to wake him up. At night he comes out and starts running on his wheel over and over again for a long long time to the point of passing out due to exhaustion. He keeps moving his bedding around in his cage in his attempt to make another burrow.
When I pick him up, he usually doesn't know what to do but just sit in my hand. I would stroke him and pet him, but he doesn't act any different than if I weren't petting him.
He doesn't like his cage, and sometimes try to climb over his water bottle in an attempt to get out.
He loves to come out and explore the world in his hamster ball and loves to find new spots in the house to take it to.
He constantly stops to lick himself and tends to chew up his toys.
