Well, that's just great. My cat is a diabetic. About a month ago we bought an off brand food that both of our cats hated. Neither one of them ate much of it, but within 5 days we bought thier normal brand. Abbey just kept losing wieght. Then she started drinking water like mad, and her urine output went up as well (duh). Dh blamed it on the hot weather, but I had my doubts. After we came back from camping I noticed lots of hair clumps all over the place, and that was the last straw. Took her in today, and got the diagnoses .She's going to get real expensive real quick. Next vet visit will cost approximately $300.00 . Luckily our vet said that we caught it early and we can try to treat it thru diet for the time being, but eventually she will have to see the vet again. We so cannot afford this , but what are you gonna do....sigh...........
