My Fluffy Cat!

I seriously think that my cat might be insane. First of all, she's cross-eyed. And she runs around constantly attacking every object at my dad's house that moves even slightly. But she's legitimately the fluffiest, softest cat I've ever pet in my whole life. I named her Google because of her eyes. It was a lot worse when she was a kitten, but they still go crossed when she goes bat-shit crazy and runs around my house at top speed just to pounce on my dog who's minding his own business. Don't even get me started on what she does when I'm trying to sleep. First of all, she'll lay on my chest/back, depending on whether I'm sleeping on my back or stomach. Then, every time I move my feet, she pounces on them. On top of that, my door doesn't have a doorknob, so it just swings open and closed, and every time i close it, she'll open it to get in or out on her own, and it's not like she can close it.
Has anyone else ever experienced this one? Cleaning out the litterbox, and it's all nice and clean once your done, and as soon as you finish, your cat walks up and immediately has to shit. I'm convinced that she does it intentionally.
