I have one named after a character in the movie 'Willow' (Madmardigan) and two named after Montreal Canadiens, at least they were when I got the cats..(Sheldon for Sheldon Souray and Mikey for Mike Komisarek and the Life Cereal kid because he hates everything but dry cat food).

My family tends to name our pets with human names rather than the tired old "fluffy" and "boots" and such.
