Mittens Kitten - attacking her toy kitten

Mittens is actually my very own first kitten (as an adult). We had kittens when I was growing up but that seemed such a long time ago. We were in for a treat with Mittens - she was always up for a game! When she first came into the house, the yellow cat in the video was smaller than her. I had won it out of a skilltester machine to give to N as a present. Mittens decided she liked it though, and as soon as she grew bigger than it, I think she wanted to teach it a lesson.
