About Kidney Disease in Cats
Kidney disease seems to be an important topic with cat lovers these days. In response to the many questions our Cat Expert receives on this subject, we decided to gather some veterinary insight and opinions about this potentially devastating illness and the effects it can have on a cat's overall health.
Dr. Scott McKay, DVM, is a staff vet with Doctors Foster and Smith, the single largest online supplier of pet products in the USA. He also participates at the Doctors Foster and Smith operated Peteducation.com. Dr. MacKay is a member of the American Veterinary Medical Association and the Wisconsin Veterinary Medical Association.
Dr. McKay, please give us a layman's explanation of what kidney disease is, and how it affects our felines.
A) The cat's kidneys play a critical role in balancing the components of blood. When the kidney is diseased, the components of blood become out of balance and illness follows.
The kidneys regulate how much water stays in the body. If the cat consumes too much water, the kidneys will increase urine production and void water from the body. If too little water is consumed, the kidneys conserve what water the cat has.
In addition, the kidneys regulate certain minerals in the blood. For example: sodium and calcium need to be held in the body at a constant level. The kidneys work very hard at keeping these two minerals in the blood and not losing them in urine. On the other hand, nitrogen, a by-product of protein metabolism, is produced in high levels by cats because their diets contain lots of protein. Too much nitrogen is toxic to the cat's body, so the kidneys must remove nitrogen to maintain health. If nitrogen levels rise because of kidney disease, the cat will become very ill.
Fundamentally, kidney (renal) disease occurs when this organ cannot regulate the components of blood. The kidneys also produce a hormone called erythropoietin, which tells the bone marrow to make red blood cells. If the kidneys are not making erythropoietin, the number of red blood cells falls and anemia results.
It is difficult, if not impossible, to maintain health if the kidneys are diseased.
What are the signs pet owners should watch out for?
Signs of kidney disease in cats include:
- Vomiting
- Diarrhea
- Dehydration
- Depression
- Bleeding disorders
- Seizures
- Mouth ulcers
Does kidney disease affect one age group more than another?
Generally speaking, older cats tend to have more kidney problems than younger cats.
What kind of treatments are available for cats with kidney problems?
It depends on what caused the problem. We classify kidney disease as either acute or chronic. Acute renal (kidney) failure can usually be treated by identifying the cause of disease (an infection or a kidney harming toxin), removing it and treating the symptoms. Chronic renal failure is a long term condition that requires long term care. In these cases the cat will need a special diet and medications to maximize its remaining kidney function.
Is there anything pet owners can do at home to support the veterinarian's care plan for their pet?
There are things pet owners can do at home to support a veterinary care plan for pets. In fact, without a strong commitment from the cat's owner, the treatments recommended by the veterinarian will fail. Essentially, it is the owner's duty to maintain the proper diet, keep up with medications and monitor the cat's progress.
What is the prognosis for a cat diagnosed with kidney disease?
For cats diagnosed with acute renal failure, the prognosis is fair/good if the cause of the disease is identified early and there hasn't been too much damage to the kidney. In addition, cats with chronic renal failure can live long, comfortable lives if their diet is closely monitored and the proper medications given. These cats need regular visits to their veterinarian to access their condition.

Hi Mary,
I'm so sorry that this happened and you lost your cat. I'm not sure what is the cause of the kidney failure for your cat, but Siamese tend to be pretty healthy as far as breeds go. I've always owned Siamese cats and they tend to live longer than many cats (my childhood cat lived to be 19). It is possible she could have had a reaction to a vaccine, to food or simply had a birth defect. You can have your vet do an autopsy and find out the exact cause, if you want to know for sure.
-- Contributed by: LoriSoardI adopted a 1 yr, 8 mo. cat from the shelter, I was told she was a Siamese Lynx Point cross. She had just had kittens (still had 2 with her, 2 mos) but was seen to be healthy. She had all her shots, she was spayed, and examined to be healthy by the vet. 7 weeks after I adopted her, she began vomitting, very depressed, seemed uncomfortable, no urinating, no eating or drinking. After 24 hrs at the emergency hospital, I told her kidneys were failing - I had to put her to sleep. Is this common in a cat so young, does it have anything to do with the breed? There were no symptoms up until the day she took sick, but the hospital said her kidneys were 3 times their normal size when I took her in.
