Rachel is a very small cat. She weighs in at 6 pounds. She is always eating, but along with that she is a ball of energy. She is always walking, running, playing or what ever. She eats a lot more than Cubby could ever eat. I go through 3 times as much food since I got her, than I did with just Cubby. I have to buy a 25 pound bag of food ever 6 weeks.
