My cat, AKA, Satan

So, last night, while I am in the shower, I find out that my cat has puked in several different places all over the apartment. Apparently, he decided to eat part of his bouncy ball. Smart. So, when I go to bed, he decides that he is angry at me for throwing up, and bites my foot. The bottom of my foot. Ohhhh not happy!! He is really the devil. He thinks its cute to snuggle and cuddle and then bite and nip. Why oh why did satan decide to live in my cat??
