Top two are the twins, Damien and Janice. They actually cuddle, like holding each other and all. (They're not all black, they're lighter brown/grey with the black on top so they actually have stripes on the sides and stripes on the back of their heads/neck.) :)

Second picture is... I believe Janice and her sister Cocoa having a little dispute. Probably over food, Cocoa is a fatty. xD

Third picture is Damien and Cocoa cuddling, see how he's holding her? Oh, and that's their sister Janice's butt off to the left.
