That's an interesting article, Fuzzy, thanks for the link!

I especially found this interesting:

"Sometimes when a new mirror is "discovered" by a mature cat, it starts to raise a paw in defense. When it sees the image do exactly the same thing, it knows it is a reflection and walks away. It reacts quite differently when another cat is on the other side of a window. Maybe cats have more recognition of "self" than we recognize.

Sounds as if they notice the difference between their own refection and another cat. Or is the cat behind a window only more interesting 'cause its moves are not predictable?

The article also explained another thing to me: When Luna was a kitten, she was interested in watching tv and she loved to play with the mouse cursor and animated gifs on the computer monitor, but then she suddenly stopped. Guess the game was just getting old and boring for her.
