Bassett was really tiny when I got her, and she has grown into a big girl - 14 lbs! Tilly is a very sleek and LOOOOONG cat.. I can't remember what she weighs but probably only 7 or 8 lbs at the most. Then there is Nutmeg.. she still looks like a kitten. I don't know what she weighs.. maybe 4 lbs, tops? I know she's getting bigger because I've had to loosen her collar, but she still pretty tiny!
