These are the best pics I have been able to take of his thumbs. I'm a proud cat servant. My kids at school call him "deformed," but he is NOT; he is unique and special. Because he is so large, one would expect him to perhaps be aggressive, but other than his rivalry with Miles, he is very laid-back. He doesn't even meow. In fact, of all my *6* cats, only Lovey talks. Everyone else except Snowflake growls (She does nothing vocal!), so it's a pretty quiet bunch. Even when begging for food, they just run to their bowls, sit, and stare.
