What causes kidney failure in cats

Kidney disease is the number one disease that affects cats which is what we are going to focus on in this article. There are over 400 different causes of kidney failure in cats but most of those are unrelated to renal failure. The main causes of kidney failure in cats are renal disease, toxic processes, and blood clotting disorders.

There is no “typical” form of kidney failure in cats, most cases of kidney failure in cats are due to a combination of factors. It is difficult to say what causes kidney failure in cats if there is no specific form of kidney failure. Most of the time, the kidney failure is not due to a single cause, but a combination of factors.

The most common form of kidney failure in cats is due to a few different diseases that affect the kidneys. The most common diseases that affect the kidneys in cats are:

1. Renal disease

(kidney failure caused by kidney disease)

The kidneys are the organs that remove waste from the blood and are responsible for regulating the amount of water and minerals in the body. If a cat has a disease that affects the kidneys, that disease can cause the kidneys to fail.

The most common type of kidney disease in cats is renal disease which is when a cat’s kidneys fail. Renal disease is the most common type of kidney failure in cats. Renal disease can be caused by a number of different things, such as:

Kidney stones

Feline leukemia

Kidney cancer

2. Toxic processes

(kidney failure caused by renal failure caused by a drug)

The kidneys also remove toxins from the body including medications that can cause kidney failure. It is not uncommon for cats to have kidney problems after taking medications. Some commonly used medications that can cause kidney failure in cats are:

Aluminum based antacids











Sulfonamide antibiotics


3. Blood clotting disorders

(kidney failure caused by a blood clot in the kidney)

Like humans, cats are also susceptible to blood clots in their kidneys. These blood clots can block the flow of urine, which can cause kidney failure. Some of the common blood clotting disorders in cats are:

Feline hemorrhagic disease

Feline immunodeficiency virus (FIV)

Feline leukemia virus

Prothrombin deficiency

Prothrombin G20210A mutation

Because the kidneys are no longer able to remove waste and fluids from the body, toxins build up in the blood, causing an overall ill feeling. Kidneys also have other functions they are no longer able to perform such as regulating blood pressure, producing the hormone that helps make red blood cells and activating vitamin D for healthy bones.

One of the first signs of kidney failure is an increase in the frequency of voiding. Because the cat is voiding frequently, it might be assumed that her kidneys are functioning properly. Actually, the kidneys are no longer able to conserve water efficiently. Cats will go to the litter box several times a day and... Read more
