What the hell is going on?

[wolfwoodglomper]

Jack has been attacking me a lot. (Jack, as in, my cat.) Like, I walk by and he jumps up and acts like he's going to pounce on my feet. Sometimes he does pounce on my feet. And he jumps up on my lap and attacks my arm, and bites it and scratches it with his back claws.

What's going on? Why is he doing that? It makes me sad. Like he hates me or something. =(
