Chronic Renal Failure in Cats
Defining CRF in Cats
Chronic renal failure (CRF) is a progressive disease caused by long-term insult to the kidneys. This over time, damages their ability to concentrate urine and remove waste products from circulation. The word “renal” means anything pertaining to the kidneys. Chronic renal failure is one of the most common causes of death in domestic cats. Unfortunately, most owners don’t notice the symptoms of CRF until their cat’s kidneys have been damaged beyond repair. Usually, by the time CRF is diagnosed, about 70% of functional kidney tissue has already been destroyed. Once clinical signs appear, the kidneys have lost most of their ability to filter waste products. This includes circulating blood, excreting the end-products of metabolism in the urine, regulating blood pressure, contributing to red blood cell production and regulating the concentrations of hydrogen, sodium, potassium, phosphate and other electrolytes in the cat’s system. Chronic renal failure is always progressive, irreversible and eventually fatal.
Chronic renal failure (CRF) in cats is a progressive disease caused by long-term insult to the kidneys which, over time, damages their ability to concentrate urine and remove nitrogenous waste products from circulation. CRF is one of the most common causes of death in companion cats. Unfortunately, the symptoms of chronic renal failure usually are not apparent until the cat’s kidneys have already been severely and irreparably damaged. By the time CRF is diagnosed, roughly
Chronic renal failure (CRF) involves a long-term insult to the kidneys that causes them to gradually deteriorate, losing their ability to concentrate urine and remove waste products from the bloodstream. The reason cats get this condition isn’t well-understood, although advancing age is considered to be the biggest risk factor. It seems that as cats get older, their kidneys simply start to wear out. Most cases of chronic renal failure in cats happen when they
Chronic renal failure (CRF) is caused by some long-term insult to the kidneys. Most cats with chronic renal failure don’t show any signs of being sick during the early phase of their disease; this is considered to be renal “insufficiency,” rather than renal “failure”. The word “renal” refers to anything having to do with the kidneys. However, as chronic renal failure progresses, affected cats become very ill. Circulating toxins are building up in their bloodstream,
Most cats that are feeling and showing symptoms of chronic renal failure (CRF) are very sick and already have lost about 70% of their kidney function. The veterinarian will be presented with an older cat who “ain’t doin’ right” (called “ADR” in veterinary lingo). Any aging cat that is progressively weak and lethargic, losing weight and body condition, and drinking a lot and urinating a lot probably will be suspected of being in end-stage chronic
Chronic renal failure (CRF) can exist but be asymptomatic in cats for a very long time – even for years. Normally, by the time an owner notices signs of renal failure and a diagnosis is made, the condition is irreversible. Nevertheless, there are a number of management techniques that can help maintain a cat’s quality of life. The goals of treating feline renal failure are to alleviate the signs of uremia (which is the build-up
