I have Lemonade (albino), FedEx (het peid), Snow (pied), Bruce (mojave), Tax (lesser), Refund (lesser), Sunny (lemon pastel), Juliette (normal...and now 'Romeo'), Cleopatra (spider), Wilson (Bredli's), and Olivia (IJ carpet).
I didn't name most of them. My 5 year old son and 11 year old nephew claim that honor. lol. I named FedEx (because FedEx lost her during shipping...), Tax, and Refund. I rarely refer to any of them by their names except for Lemonade because she is my son's favorite.
As for the name 'Snow,' I actually have THREE animals in my care named 'Snow' currently- a python, a chicken, and a breeder rat. Apparently 5 year olds aren't original and if it is white or has white on it, there's a good chance it will get named 'Snow.'
