Kirsten, I've been wondering about that too. The first time we put a mirror in front of Fister, he seemed a little confused to see a cat in there, and he was very interested in investigating behind. He lost interest pretty soon, though. If we hold a string and drag it behind a door, he often look for the hand dragging it instead of the end of it, and if we run around from one room through another and then along the corridor to the starting point, he will often be standing there waiting for us to show up with it and then go for it. So we think he's a smart guy!!

He is also communicating quite a lot. When he's been to his litterbox, he usually tells us and if he's seen a cat outside from the window, he runs to us, chatting away about it! So cute!!
