Well, I gave all my pets Twilight or Hunger Games themed names...so why don't you name the ferret after your fave movie or book? BTW, in case you were wondering, my pet names were: Alice, Hale, Effie, Cullen, and Mitch (short for Haymitch).
Angel, holly, ariana, Cynder(or Cinder.) rebecca, Elena, mallory,McKayla, Marlena, Tori, Lexi,Alice,Trinity, and nevaeh(heaven backwards) are unique and pretty sounding. :) obviously your choice but these are some suggestions. :)
