Kidney Disease In Cats And How It Works?

Kidney Disease In Cats

Kidney or chronic renal disease in cats is a top cause of mortality. The kidneys essential for eliminating waste products in the body, concentrating urine, and balancing water and electrolytes such as salt in the body. If the kidneys malfunction, it can result in two types of disease Acute or Chronic.

  • Acute kidney Disease can grievously damage the kidneys and may cause sudden death. Aggressive treatment at a 24-7 veterinary facility is typically required to help minimize the risk of death.
  • Chronic kidney failure often called chronic renal failure or CRF occurs slowly and cats may be able to compensate with this for months to years. Signs may be milder and more progressive. With an appropriate diagnosis, nutrition, monitoring and treatment cats can potentially live with chronic kidney disease for years.

Clinical signs of chronic renal failure in cats include excessive drinking, excessive urination such as larger clumps in the litter box bigger than the size of a petite females fist.

Muscle wasting especially over the back, weight loss, bad breath due to kidney poisons building up in the blood and causing ulcers in the mouth esophagus and stomach, sudden blindness or dilated pupils unusual appearance to the eyes due to high blood pressure and retinal injury, drooling, lethargy heat-seeking due to low body temperature, dehydration is seen as excessive skin tenting, pale gums secondary to anemia, decreased appetite, hiding, weakness and twitching or seizuring in severe undiagnosed cases.

Diagnosis Of Chronic Kidney Disease

Kidney Disease In Cats

The diagnosis of chronic kidney failure in cats is based on physical exam and blood and urine tests. According to me, any cat over the age of 10 should have a blood test when visiting the vet, yes, that is once a year.

This should include the following tests:

Complete Blood Count

A complete blood count or what we call a CBC which looks at the red and white blood cells, looking for anemia and looking at the platelet count.

Chemistry Panel

A chemistry panel which looks at the kidney and liver function, salt balance, blood sugar and protein.


Urine analysis obtained by aseptic technique or so-called Sisto synthesis, which searches for the presence of red blood cells and white blood cells in the urine, and the presence of proteins or bacteria in the urine.

Thyroid Test

The T4 or thyroid test can see if your cat’s thyroid is overactive.

Urine Culture

A urine culture the most accurate way of detecting if there’s a bacterial urinary tract infection or a UTI.

Urine Protein Creatinine Test

A urine protein creatinine test often called the UPC to look at the level of protein lost in the kidneys.

Blood Pressure

A blood pressure which should be approximately a hundred and twenty millimetres of mercury very similar to human beings and very rarely kidney biopsies.

Most importantly my veterinarian is looking at three main tests (BUN), creatinine and the urine specific gravity which is the kidney’s ability to concentrate urine, with normal being greater than 1.050

Most of the time elevations in the BUN, creatinine and another test called the SDMA indicate kidney disease and should be evaluated acutely by your veterinarian. If the amount of intravenous fluid in the cat is raised, it may require hospitalization to minimize the results of these kidney tests.

Can These Blood Tests Elevated From Kidney Poisons

Keep in mind that these blood tests may be elevated from kidney poisons such as Easter lilies or other types of lilies from temporarily being unable to urinate from a urinary obstruction or even from underlying kidney infections what we call a pyelonephritis which is when a urine tract infection starts in the bladder and migrates up to the kidneys.

Elevated blood tests or abnormal results may want additional testing, these may include x-rays of the abdomen to rule out kidney or bladder stones or even an abdominal ultrasound to look at the architecture or inside of the organs.

Is There Anything You Can Do To Prevent Chronic Renal Failure In Cats?

Frankly speaking, it is not true. Chronic renal failure is usually caused by scars, injuries and even underlying genetic causes.

There are a few things you can do to minimize the risk of chronic renal failure in cats including:

  • Keeping poisons like Easter lilies or any plants from the Hamrick Alice or Lilium species out of reach.
  • Making sure your cat has fresh water available at all times or even bottled water if you use well water or potentially high mineral content water sources.
  • Wean cats, especially canned food as they get older, since you can gradually increase their water intake by adding warm water to canned food.
  • Making sure your cat gets an annual examination at your veterinarian especially as they turn over 10 years of age and lastly
  • Getting annual blood work done at your veterinarian including annual blood pressure.
