Causes
Ageing, genetic predisposition, previous illnesses, hypertension, infections and toxins. In cats it is very common from 7-10 years of age onwards.
Diagnosis
Blood tests (urea, creatinine, SDMA — the latter detects the disease earlier) and urine tests. Early detection greatly changes the prognosis.
Treatment
There is no cure, but treatment slows it down: a specific renal diet, control of hydration, medication for blood pressure and phosphorus, and fluid therapy. With good management, many animals live for years with a good quality of life.
Prevention
Annual check-ups and blood tests from 7 years of age (key to early detection), water always available, and avoidance of substances toxic to the kidneys.
