Kidney disease killing cats

2012-05-09 19:21

Los Angeles - It's one of the leading causes of death for cats, but there is no cure and no known cause: kidney disease.

One in 12 older cats has chronic kidney disease, according to Banfield Pet Hospital's just-released 2012 State of Pet Health Report.

Banfield, the largest veterinary practice in the world with 800 hospitals in 43 US states, based its report on medical data from more than 2 million dogs and nearly 430 000 cats seen by its veterinarians.

Acute kidney disease, caused by eating antifreeze, grapes, lilies or other poisons, can be cured if treated quickly enough. "If you catch it, you can treat it," said Dr Nina Nardi, chief of staff at Banfield's Canoga Park hospital, 40km northwest of Los Angeles.

But chronic kidney disease is much more common, more progressive and irreversible, she said. Treatment is aimed at easing pain and prolonging a quality life.

Cats diagnosed in the early stages of chronic kidney disease live two to three years, while those diagnosed in later stages live only a few months. (Dogs can get kidney disease, but it is seven times more common in cats.)

Nate Glass can only try to ease the pain of his cat Girly, who he rescued as a kitten after she'd been shot with a BB gun in an alley behind a dollar store.

Nardi, Girly's vet for the past five years, tested her for kidney disease because she lost 1.3kg between exams.

"It shocked me," Glass said. "I didn't think she was three pounds lighter. She still looked as fluffy as she ever did."

Cats are notorious for hiding their health problems. Possible signs of chronic kidney disease include increased thirst, increased urination, decreased appetite, weight loss, vomiting and bad breath.

The first thing vets do for a cat with chronic kidney disease is hydrate it, Nardi said. "Fluids reduce the filtration load on the kidneys," she explained.

Sick or not, Nardi recommends recyclable water fountains so cats always have access to fresh water. But water won't restore kidney function, just help what's left work better, she said.

She put Girly on an IV for three days, prescribed a special diet that cut down on protein and salt and made sure she had medicines for nausea and vomiting.

Girly now goes in twice a week for subcutaneous fluid treatments, where the liquid is injected beneath the shoulder blades.

Kidney transplants can ease pain and help a cat live longer, but they are rare and cost between $8 000 and $18 000, said Dr Chad Schmiedt, the surgeon in charge of the transplant program for the University of Georgia's College of Veterinary Medicine.

Watch your cat, Nardi advised. Too often, a dog will throw up once and its owner rushes to the vet, but a cat might throw up every day and no one will take it in, she said.

And she thinks love and attention can be almost as important as water. One of the worst cases she ever saw was a cat in the late stages of the disease.

"You wouldn't have given her more than six months," she said. But the cat had a special owner, she said, and lived for 2 years.

    Let the record show that since the "high quality" cat foods, found in Vets practices, have hit the shelves there was an increase in kidney disease cases. While cats that eat the same food as humans still live to higher ages like 16-22 years.

      Please provide scientific proof for your statement. Chronic renal failure in cats have nothing to do with diet,and there is no proof that cats live longer on human food. cats are carnivores,not omnivores like humans,thus human food is not at all suitable for cats.

      Jacques Pieter du Preez - 2012-05-10 04:14

      the only reason that renal failure cases might have increased after introduction of better quality food is the simultanious advancements being made in vetirinary science regarding the ability to acurately diagnose and treat diseases.

      @ Jacques. Thank you for this comment. In fact it has proven, through peer reviewed scientific research, that a good level of high quality, highly digestible animal protein is necessary for muscle support and good balance of lean muscle mass (not too much fat). In the mid 90’s it was shown by Delmar Finco (renal expert) and I think Dennis Chew that high (50+%) protein diets do NOT cause kidney failure and once kidney failure is present high (50+% animal protein) does not accelerate renal failure. It is the Phosphorous in the diet that accelerates renal failure.

    i imagine vets will be overbooked now, lots of money for the medication too..

    I have the same suspicions as you do Francois, but I view all commercial dry cat foods as possible problems, "high quality" or the supermarket variety. Of course this idea is merely a hunch and based on personal observation of a very small number of cases. The alternative is fresh meat including occasional additions of organ meats since cats are indeed carnivores and certainly in my experience will refuse to eat other "human" foods of vegetable origin.

      Hahahaha .... you gotta see the village cats here in Thailand. Invariably they are fed nothing but boiled rice and left to their own devices for the rest of their dietary requirements. They certainly look pretty healthy though!
