My cat (Gidget) is 18. 4 years ago she had kidney failure but has been great since then. I feed her Hill's k/d dry food which she has always eaten well. I've always fed her a Tbls. of meat Friskies for breakfast and very little table food other than milk or cottage cheese on occassion. I had her to the vet the other day and she now weighs 3 1/2 lbs. She's always been a little cat but has lost way too much weight. The Vet said the k/d gives her nutrition but does not put on weight. I am to feed her meat food 3 x's a day. She doesn't like k/d meat so am giving her Science diet 7 . The problem is it's very expensive. Is there something I can make for her? Can I give her Half & Half for lunch? She doesn't have a lactose problem. Thanks!
