Here's a fun video of cats leaping for Leap Day. At least you can see in some of the jumps the cats and kittens weren't hurt, which I think makes the leaps more enjoyable. The ones where they scare people are the best.
I also have to admit that them pouncing the toddlers is hilarious. I'm probably going to hell for that, but it's still really funny. Some of those cats are as big as the kids. Leap Day is fun!
