Interesting video!!
Cats love activity too, especially when given food afterward. My cats love to run down the hallway with me, they love the toys I bring out, etc. I would not have the slightest idea how to train them, but I do know people who have trained their cats on a leash, or to go to the bathroom on a toilet.
I too think cats are smart. They train each other. In fact, I know from whence I speak on this last statement- Buddy, my 5 1/2 year old cat, has taught Oliver, my two year old cat, how to do these trapeze jumps on the bed anytime between 5:30 and 6:00 a.m. Buddy just sits by and watches, as if he has not the slightest idea what is going on.
The only training I have for that is to put them in the office/library and close the door.
