Signs of Renal Failure in Cats

Renal failure, otherwise known as kidney failure, is a common problem in older cats. Infections, genetic disorders, inflammation and cancer can cause this dreadful disease. Unfortunately, according to the Healthy Pet Journal, many cats don't show symptoms of this kidney failure disease until 70 to 75 percent of kidney function is lost. While renal failure symptoms can mimic other diseases, it is important for cat owners to watch for signs and symptoms. With proper treatment and a good diet, some cats can live a long life.

  1. Appetite and Weight Loss

    • One of the first signs of renal disease in cats is decreased appetite and weight loss. Since the kidneys aren't working properly, cats typically don't have a hearty appetite and lose weight. Dr. Scott Brown, a veterinary medicine professor at the University of Georgia, recommends warming smaller amounts of food and varying the cat's diet gradually to maintain a healthy weight.

    Increased Thirst and Urine

    • More urine is producedsince because the kidneys are working less efficiently. Unfortunately, production of urine with renal failure requires lots of fluids. The Healthy Pet Journal recommends that cats with these symptoms eat foods that are moist, which helps prevent dehydration.

    Lethargy and Depression

    • Lethargy and depression are common in cats with kidney failure. Chronic renal failure saps the body of important nutrients and contributes to anemia. Oral vitamin supplements can be given to cats, although their effectiveness is limited.

    Vomiting and Bad Breath

    • Failing kidneys can't digest proteins adequately, which can lead to foul smelling breath and vomiting. Antihistamines and a low protein diet can help alleviate these troubling symptoms.
