I had a cat like this once. She looked very similar to the cat in the avatar - she was black and tiny even when she was fully grown. Her claws always stuck out a little bit even when she was sleeping. I thought that maybe it was because she was so small that her claws just couldn't fit inside of her itsy bitsy toes. I know that my reasoning is whimsical, but then again, who knows? I would never ever suggest to declaw a cat because they are a natural defense for them. What if the cat got outside and a dog started chasing her? The first reaction for a cat is to climb a tree to escape and without claws this becomes impossible and hence, unsafe.
