Playing "Cat"

Last night I was doing things upstairs and yelled down to ask Alex what he was doing. He said "I'm playing cat with Scooter". Sure enough, he was crawling around on the floor after the cat, doing everything he did. I believe at one point I even saw him drink out of the water dish, gross! This game went on for a long time...I think until he started chasing the cat around the house as he tried to escape Alex!
