A Zhu Zhu is a mechanical hamster that comes in a wide variety of styles, colors and formats. It runs all over the place and changes directions when it comes in contact with anything. It has a large vocabulary and squawks & squeals while interacting with your pet.
The prices range from under $6 to over $25 depending on your choices. I hate when I sound like a commercial so be assured I have no affiliation with this product. I simply think it’s the greatest buddy you can buy a pet.
