My dad had a book when he was younger, and it had a cat in it called Hazeratz. I think the book was in German, and it sure sounds like a good German cat name, don't you think?
Anyway, for some reason, my dad would refer to random cats as Hazeratz the Cat. In my mind, Hazeratz is a solid grey kitty with those golden eyes staring at you. Now, if my dad can't remember a cat's name, he just calls it Hazeratz.
