I noticed my cat was drinking lots of water. In am a stage 4breast cancer patient and I am really attached to my. Fur baby. She was then sitting by water bowl. Her fur looked good but not as pretty as usual took her to vet he said he did not think renal maybe thyroid. The early call next day told me otherwise. Her creaton was 2.8 and bun 36. He put her on KD which she loves. She has begun to drinknless water but fur still not as pretty as it was. I bring her back in a month to check numbers. Does anyone know how this is going to go? I just can't think of the worst....can she stabilize? He was very vague.
