Thanks everyone. I too have a "fluffy" girl and I picked up some good information, but what do I do if I have one "fluffy" girl and one thin girl? How do i keep from lucy eating oni's food? I adopted them both together and they are very close. They even enjoy eating out of the same food dish. I've tried giving Oni some extra food without lucy, but she won't eat unless lucy is there and lucy always knows when food is being presented. Sigh. Lucy is almost 6 years old and her tummy is really getting big.
