Attached is a photo of my 19 year old cat, Heidi. I've had her since she was 2 days old!!! On August 23, 2011, she was diagnosed with severe renal failure. She was down to 3.2 lbs (right now she's just over 4 lbs). She has to have IV fluid therapy every day (by me) along with Maalox and famotidine so she doesn't get ulcers. She's on prescription food prescribed by the vet (Royal Canin and Hill's) which she was eating for a while. Then she wouldn't really eat too much. She just ate her meat baby food. Sometimes with pumpkin in it to help her "digestive" problem. Since I work at Petco (in the grooming dept), I was asking around and looking at all the different foods. A food specialist, Heather, always seems to recommend Natural Balance for the dogs that come in to the salon. So I bought a can to try on her. Ultra formula. She loved it!!! For the past week, in addition to her IV's and medicines (and her baby food as breakfast and late nite snack!), I have fed her the Natural Balance. What a difference!!! She is peppier, plays (a little) with her five 1-1/2 year old siblings, and runs (sideways sometimes!) up her little steps to go onto the couch! She even goes underneath the christmas tree to lay down and sleep. She hasn't done that this season at all!!! I haven't seen her this peppy since before she was sick. I know she's supposed to eat the prescription food, but if she won't eat it, what's the point?? At least she's eating!! I know her time with me is short and I want to make her last days the happiest times (for both!), so I really do appreciate your great product.
