When a cat suffers from kidney failure, the usual clinical signs are abnormal manifestations such as drinking more and urinating more, drinking less and urinating less. Most cats will also have nausea, vomiting, abdominal pain, diarrhoea and weakness. A blood biochemical examination of the cat will often reveal hypertension, anaemia and hypohaemoglobinaemia. Also in the biochemical examination, the renal function index can be seen with blood glucose and blood phosphorus levels significantly above the normal range, and creatinine and urea nitrogen levels increase. Through routine urinalysis, proteinuria, haematuria and purulence are often seen in cats. Generally speaking, acute renal failure is easier to be detected by the owner, while chronic renal failure often develops to a very serious stage before there are obvious symptoms. When the owner finds out that the cat has kidney failure, the cat has already experienced serious weight loss, so it is usually difficult to cure chronic renal failure completely.
