Great news, Kirsten! Their body shape does start to change as they get older. Tubby used to be a sleek, all muscle furball. Now he looks like an old man. You can tell just by looking at him that he's an older cat. Not much you can do about it except maybe get a kitty treadmill for them. Peanut on the other hand, has her long hair to hide any body changes so she still looks like a teenager instead of the old lady that she is.

Oops....OUCH!...Peanut, watch the daggers!....sorry...didn't mean to call you an old lady. You're my little sweety pie, you know that. Now let meowmy go get a bandage...or two or three.....
