What happens to a cat with kidney disease?
The kidneys have a lot of spare capacity for filtering blood, so symptoms only appear when about three-quarters of the kidney cells have stopped working. One of the first indications of disease is the loss of ability to produce concentrated (dark) urine. So to get rid of the same quantity of waste material your cat has to produce larger quantities of more diluted urine. Your cat will be thirstier than usual and have to pass urine more often. As the disease gets worse other symptoms may appear. Your cat may seem depressed and lose interest in food, vomit regularly, lose weight and its coat becomes dull. You may also notice bad breath and ulcers in its mouth. In the very final stages of the disease your cat may go into a coma.
