Random thought about my cats:

[camwyn]

If my sister hadn't already named them Tiki and Shula, the names Jacob and Esau would probably be appropriate. One is bigger, stronger, hairier, and has quite a lot of red to his fur. The other is smaller, quieter, friendlier towards people, and better at conning food out of people.

On the other hand they're both eunuchs so maybe the whole patriarch naming scheme isn't such a good idea.
