Hello dear hamster lovers! My hamster used to run at his wheel until I buy a new, bigger one. Previous one was small for him so I bought a new one but he just doesn't run in it. He climbs on it and then just sits, or climbs over the wheel instead of running in it. It has been two or three days that I bought this new one. He basically does not care.
Today I also brought the old one in his cage, now he has got two wheels. He still doesn't seem like attracted to any of them. Is it normal? Which one should I keep?
