Kidney Disease In Cats

Kidney disease and my cat

The kidneys are a vital organ whose main functions are to remove waste products from the blood and keep us hydrated. They also play a part in electrolyte balance and red blood cell production.

What do my cat’s kidneys do?

The kidneys play a vital role in removing waste products from the bloodstream, retaining essential nutrients such as potassium, maintaining hydration, and producing urine.

What is chronic renal failure?

Chronic renal failure is a condition where over time, the function of the kidneys deteriorates. This results in the body’s inability to remove waste matter and purify the blood. The signs that your cat is experiencing kidney problems will likely only become obvious when the disease has already progressed. Being aware that this is a common disease will assist you in spotting the symptoms earlier.

The signs

Cat’s usually show no signs of disease until 75% of their kidney function is gone. This means by the time your cat shows obvious signs of the disease, it could already be in the advanced stages.

Excessive thirst and increased urination are the main signs that you’re cat’s kidneys aren’t functioning properly. However, diabetes mellitus, hyperthyroidism, and liver disease are a few other conditions that share these symptoms. It’s always best to let a vet give a proper diagnosis. Other signs could include:

  • weight loss
  • poor coat quality
  • increased urination
  • inappropriate urination
  • incontinence
  • excessive drinking
  • vomiting


Cats are particularly prone to kidney damage, and it has a variety of causes. Infections, cancers, exposure to toxins, and malfunction of the immune system may all be responsible for starting a slow process of damage, leading to kidney failure.

Kidney disease (or chronic renal failure) is the most common medical disease affecting cats. It is mostly seen in cats over the age of three.

How is renal failure diagnosed?

Renal failure is usually diagnosed by a blood test and urinalysis. These tests help to determine the extent of the disease, allowing your vet to proceed with the best course of treatment.

Can renal failure be prevented?

The risks associated with chronic renal failure can be minimised by maintaining good hydration and a high-quality diet. While keeping good hydration, it is important not to force your pet to drink excessive amounts. There are many good filtering and flowing water bowls available that can help encourage good hydration. Once kidney disease is diagnosed, there are many specific diets available which can help support the kidney to maintain good function. The key is early diagnosis – so make sure your pet is having regular screening tests.
