"Smart" Treadmill for cats

[Catherine]

I agree with Sally Cat. The little laser pointer is interesting for a few seconds. After that it is just a dot of moving light.
I can't imagine a cat being interested in a treadmill. It is a lot like a hamster wheel. Hamsters have simpler tastes. They like running for the sake of running. Cats need something more stimulating. 

Better cat food would help with the weight problem. Chasing around and playing with the cat would help too. It would help the person to be healthier. Watching a cat run on a tread mill is not exactly a workout for a human either.
