Clem (Clement). These are pope names, but Leo is also my favorite uncle's name, and Clement was my grade school, and Clem is just cute, isn't it? I think Leo and Clem has a nice ring to it.

Plus a friend of mine had 2 girl ginger kittens in the mid 90's, and she called them Thelma and Louise - I cut out pics from People magazine of Geena Davis and Susan Sarandon & the movie and made them a laminated placemat for their food & water dishes.
