Reduced kidney function and CRF are common in older cats. Early signs like decreased appetite, weight loss, increased water drinking and urinating can be subtle and appear slowly over time. Most cats are not diagnosed with kidney disease until 2/3 of their kidney function has been lost. Feeding a low phosphorous diet, administering Sub Q fluids, using a phosphorous binder and kidney supplements can improve your cat's quality of life.
