We named her Trillian, mostly inspired from the character in The Hitchhikers' Guide to the Galaxy series of books.
He is Diogenes. Inspired from an antagonist in the Pendergast series of books, but hopefully he won't be as evil as his namesake. :-) After some reading on Wikipedia, we deemed it fitting after reading about Diogenes of Sinope, a greek philosopher. One of the few men to publicly mock Alexander the Great, and lived to tell about it. Bold name for a bold cat.
