Man why would someone euthanize a kitten just because it looks different? People suck so much. I'm glad Frank&Louie got a loving home and a reasonably long life for a cat.
Yeah, II might assume that a cat like that is in a lot of pain, if I just hadn't seen the video of the cat playing Now that I know better, I'd be sure to name him something disturbing. Leatherface, probably.
My first girlfriend used to petsit for a parrot. She used to get him high by blowing potsmoke in his face (this was in the 70s, before I met her. I do not endorse this behavior) When stoned, he would swing back and forth and sing "O Sole Mio".
