appreciate 1 yr old black and white hamster. 2 cages customized to join so he has lots of space to stay active. includes his sleeping quarters which is added onto cage with tubes,2 exercise wheels one inside one on top, 2 hamster balls for roaming the house. he's a bit timid but friendly and doesn't bite. trained to get right into and out of the balls. only decided to rehome due to the recent arrival of 2 large cats and I am worried about his safety.
