i love kittens this age, cuz you can go "hey!" and snap your fingers, and they all look up cute and innocent all together (execpt the stray yawner of course) so you can take a picture, but when cat's are older you go "hey!" and snap your finger and they look at you for a second, notice you dont have any think of interest, namely food, and they look away when you're trying to take your picture... xD i love them.
The one with his mouth open doesn't look like any of the others. He's all brown and has no white on him. They kind of remind me of my cat Ghana, she's a gray/orange tabby/brown and orange calico with a white belly and muzzle. She's definitely one of kind.
