Cat Running Wheel

I recently stumbled on The Cat Wheel, a well designed infinity treadmill for your feline (and small canine) friends. It is, ostensibly, for cat exercise but after watching this video of it in action, it's clearly for human amusement as much as any other purpose it serves.

I think there are actually several products out on the market. The One Fast Cat project seems to be the most affordable but the Go Cat Wheel looks a tiny bit better as the base is more concealed (tho it is twice the price).

That's a lot of info for a cat exercise device. Long story short, just find some videos of it in action and enjoy the rest of your life.
