CRF can only be accurately diagnosed with clinical tests. There are some symptoms and behaviors that indicate the likelihood of CRF and, if these are observed, the cat should be tested as soon as possible.
The most telling signs are increased thirst (polydipsia) and excessive urination (polyuria). As the condition progresses, your cat may experience loss of appetite, nausea and vomiting, weight loss, poor hair coat and emaciation. Only 30% of kidney capacity is needed for normal functioning. Therefore, no symptoms will be seen until approximately 70% of renal function is lost. It is important to begin treatment as soon as the first symptoms appear.
Even with diet control, drugs and fluid therapy, you will eventually see at least some of the symptoms on the following list. Not all cats will exhibit all symptoms.
