Q: How is a fallen angel like my little girl kitty's fluffy coat?
A: They're both Lucy fur (Lucifer)!
I never said it was a *good* riddle. :-)
Congrats to samantha2074 & redstarrobot for guessing correctly and to redeem147 & drox for getting very close with "loose o' fur." :-) Nice try, drake57, with your guess. :-)
