@Nannycoe1: We often say that our boy is the color of smoke. He blends into shadows.
I've also got one that looks like that. His name is Ratatouille named after the rat in the movie. My friend (that owns 3 cats) originally had him. Since she loves to cook and works in a liquor store, she tries to name her cats after a food. So since ratatouille is a food as well as a gray, furry character in a movie, she decided to go with that. She was also considering Smoky G (as in Smoked Gouda) but after hearing from some other friends, decided to go with the former. And actually after seeing his personality, I think Ratatouille works best... When I think of "Smoky G" I think of some blues / jazz musician, just acting mellow and laid back. But my cat is always curious and tends to get into trouble because of that, just like Ratatouille from the movie.
The first time I heard him chatter, I first thought that there was a raccoon or squirrel in the house; I never knew cats did that! Then I found him crouching on the kitchen table, tail whipping back and forth, staring avidly out the sliding glass door to the hillside in back where several birds were pecking away in the grass. Now I know that when I hear him do that, he's hunting. It's interesting that cats do that as a signal that they're hunting, esp. since most of their hunting tactics relies on stealth, sneaking up on their prey and then pouncing. You'd think that the chattering would be counterproductive...
Now, what you need to do is sit down and watch a documentary on wild cats, like lions, cheetahs, and tigers. Some of the big cats make noises very similar to the chatter when they hunt. Disney has a great documentary about big cats of Africa.
Most of my cats get named after characters in books, gods or goddesses, or after something weird. We once adopted a kitten that some people had outside of a grocery store. A family had a bunch of kittens in a big box and were trying to adopt them out. We took one home and named him Box!
The kitten I will be getting is named Verschrankung. We call her Vera or Weevie for short. My daughter's cat had kittens. This is interesting, though. Her cat is the grand-daughter of a cat I had that passed away just over a year ago. His name was Bigwig. Her cat looks a lot like Bigwig did. The kitten I am taking also looks a lot like Bigwig. (They are a Turkish Angora Mix.)
Bigwig was the great-grand nephew of my cat Osiris. (Osiris is an old cat and he is still alive. But I think he may be in his final years. ) This makes Vera the great-great-great grand niece of Osiris.
