Bipolar Felines

Have you ever just been sitting on the couch minding your own business and a cute little fuzball of a cat comes over all on it's own and lays in your lap. Now you get used to calmly petting this tabby cat as it's licking your fingers and all of a sudden it freaks out, bites you and scratches you all up until you let it run away. Some people think this is normal cat behavior but no one would let a human get away with that kind of an outburst. They would immediately be classified as bipolar or having some kind of a disease. Can cats be bipolar? I don't see why not so, I think it is time for someone to experiment and give a cat some medicine. Make sure to watch it closely though, it might get depressed and eat it's way to happiness.
