Our cat is quite sporty, and obsessive, so she fits in with us even though she is a cat. For several months now she has stolen plastic bobbins from my sewing room and taken them to the entry way for a round of hockey. She will play for hours, to the point that Bill as to take her pucks away so we can sleep at night. She likes to put the pucks in nearby shoes, I guess it's to score a goal. Who knows why cats do the things they do. I found a puck in my running shoes last week when I took them out of my bag at the gym. She also likes to put the pucks in hiding places and loudly meow until we find them.
Here's a short video from round 2 of play this evening.
