IQ test for cats!

I will have to try this out on my black cat when I get some time, she's a complete goofball. I've seen her do some stuff that had me thinking that she might be a little *special* if you know what I mean. For example, she likes to sleep in the window. But when it's closed, she will still try to jump up into it, bouncing off the glass and hitting the floor all confused. I've also seen her roll off of stuff when she's laying on her back and stretching.
