I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
Cats. All the ones I've come across until now don't like being touched on their ears, specifically the tops of their ears. They twitch, or just plain run away. Dean, though, will let you rest your finger on his ears.
I was talking to someone who was like, 'that was just your sister's previous cat, and a couple you knew.' So, I know I could research this, but kitty talk! For anyone who owns/knows a cat, do they let you touch the tops of their ears?
