One Fast Cat Exercise Wheel

 A bored cat is an unhappy cat, and without a stimulating environment, cats can get bored quickly. The cat exercise wheel gives cats a safe outlet for energy that would otherwise manifest in destructive or unwanted behaviors, like clawing at the furniture, racing through the halls, or harassing their humans. 

Being entirely cat-driven, the cat exercise wheel needs no batteries or power source, and it can be used by the cat without any assistance. Some training will be required cats do not have a natural instinct to run on a wheel but once your cat learns how to use their new toy, they'll hop on it throughout the day, usually going for a quick sprint or two every few hours.
