Hi Audery, what about the vet prescription diets, has your vet recommended a can food for your boy, as the vet diets have been made especially for kidney failure & other illnesses…a vet diet would be the best at this stage especially with chronic kidney failure & will probably help him the best…..its sad when they get old & sick poor boy… My 14 year old cat had an operation 2 years ago, a cyst was wrapped around 1 of his kidney & was filling up with urine & was crushing his kidney, the vet had never done this operation before as it was very rare what my cat had but the vet cut the cyst & stitched the cyst to the side wall, so the cyst can’t fill up with urine, now the urine just runs free thru his body & the body absorbs the excess urine..
