"I bought this product in hopes that my Dwarf Hamster "Hampton" would like it. He really enjoys looking at himself in the little mirror. Although, he will not go into the bed. I don't know why. I put treats in there and he goes in and eats them, then comes out. He may just need to get used to it. (probably just my hamster.) Try it with your Gerbil, Mouse, Hamster. Overall the product is cute and very colorful."
