I have four cats...well, five at the moment, but the fifth one is a kitten that we're not gonna keep (as far as I know), but are just raising until she's old enough to be weaned.
The four cats are a seven/eight-year-old "gray calico" (as I've heard her be called..she's got gray, brown, and peach-colored fur), a six/seven-year-old siamese mix (though you can't really tell she's part siamese by now, since she's so dark), a year-old black and white cat, and another siamese mix (who actually looks siamese) who's also a year old.
Then the kitten is an adorable little black kitten with brown spots/streaks in her fur. :D I'm thinking she's tortoiseshell coloration, but I'm not entirely certain...
