I think Thomas has some sort of chemical imbalance. He's sporadic with his affections. One second he's happily purring while I pet him, and the next he is trying to devour my hand. It's not just me. He does it to everyone. We all have been scratched and bitten. So has the furniture and carpet. He attacks us out of nowhere and sinks his claws into our legs. I swear I can hear his evil cat laughter while he runs away to hide.
