Smokey runs so long on his wheel I sped up the video so as not to bore anyone:). I admit I never get tired of watching him run. Below are more videos of more cats enjoying a run.
The Ferris Cat Wheel from ZiggyDoo, along with many other cool items for cats and humans, can be found on ZenByCat's online store Cat Stuff. Every sale generates a donation to help end FIP, and every item is tested and approved by Smokey and his 23 housemates. Just look at them testing the wheels:).
