Veterinary Care: Kidney Disease in Cats

The kidneys of your cat have a variety of purposes. They remove waste from the blood into the urine, control the levels of essential minerals within the body, regulate the water balance and blood pressure, produce specific hormones, and filter waste materials from the blood into the urine. They build up waste within the circulation when kidneys don’t function properly, and the body attempts to compensate for the loss of other functions. When too much kidney function is diminished, and your pet is sick, it’s a sign that something’s wrong.

Kidneys may be destroyed by chemical substances (such as antifreeze) and infection or injury and stop operating unexpectedly. It’s more usual for senior cats to stop functioning as they age. There is no reason not identified in most cases because it was undiscovered until kidneys started to fail.

Causes of Cat’s Kidney Disease

The indicators of disease in your cat are caused by the kidneys’ inability to perform their many functions properly. An overview of the leading causes of renal diseases can be found below. The tests conducted by your doctor will focus on these areas.

Infection of Kidney Tissues

The kidney disorder that could benefit from the best chance of recovery is a kidney infection caused by bacteria or fungal species, so your physician will be looking for it. In the case of Pyelonephritis, in the first place, the doctor aims to get rid of the germs which cause destructive inflammation.

This will help you heal the damage caused by acute renal damage or slow the progression of chronic kidney conditions. A bacterial urine culture and susceptibility test will verify the severity of the disease and identify the appropriate medication.

Kidney Stones

Kidney stones can occur in cats due to a range of reasons. The many factors eventually determine the kind of kidney or stone that will form. The type of stone will affect the treatments that might be successful.

Small kidney stones in cats may show no symptoms at all. As a so-called “incidental” discovery, kidney stones might appear in abdominal x-rays for non-related reasons.

Your physician may regularly monitor kidney stones that permit normal urine flow but are left untreated. If the stone grows very large, or if tiny fragments break off and become lodged within the ureter, discomfort is likely to develop. Consult your vet for cat care plans.

Kidney Blockage

Kidney stones can break off and be transferred into the ureter. The long thin tube connects every kidney to the urinary bladder and urine. They’re likely to cause discomfort during their travel. The risk to the kidney should they end up in the ureter, obstructing any kind, either complete or partial, is a significant issue.

New urine cannot easily escape the kidneys and backs up, causing the kidneys to increase in size. The kidneys expand (hydronephrosis) and are injured after exposure to high pressures. It might be fatal when both ureters are blocked simultaneously. Visit your veterinarian for details about restorative pet dental care.


It’s not the only home ingredient that might hurt the kidneys. When cats nibble, lick, or chew true lily’s petals, pollen, leaves, and the vase’s water, it can result in significant kidney damage.

Cats, known for their sensitivity regarding food and nearly all other things, will still consume drugs sold on the store shelves or on the floor. Therefore, be sure to store any medications inside cat-proof containers. Always consult your vet before taking any medication.


The condition is known as a familial renal disease in the Abyssinian and Persian breeds and is also showing up in more upscale species. It can cause irreversible structural changes; however, they don’t cause illness until later in life. 

Many laboratories offer polycystic kidney disease DNA testing. This allows responsible breeders to steer clear of breeding animals with diseases. Visit a vet clinic for info about puppy wellness checks.
