I dunno. It looks like one hell of a scary cat in the second pic!
I have had a few cats (four)....one of them LOVED biting my fingers, but unlike the others, it was never playful. He was a mean, tough kitty. Alas, one day he snuck outside through a window and was ripped apart by some dogs.
:-(
I no longer keep cats around. All four of my cats died horrible, tragic deaths. My last cat died 4 months old of food poisoning (which I just can't understand). It threw up around 15-20 times in 24 hours. Took him to the vet, got him all his shots...did everything I could.
I can never forget the horribly painful, agonizing way he started throwing himself around just before he finally slipped away. It bummed me out for a long time....I've given up on the idea of pet cats for now.
