What You Should Know About Kidney Failure in Elderly Cats

Kidney failure in cats is a progressive and silent disease that affects one in three 10-year-old pussies  , and more than half of those over 15 years old. Also known as kidney failure, it causes a gradual deterioration of the kidneys that usually manifests itself when the damage is already irreversible.

A silent enemy stalking old pussies

As in all silent illnesses, the signs are nonspecific. And, unfortunately, when relatively clearer signs appear, the deterioration of kidney function is usually worrying. At this point, 75% of the kidneys are already affected.

In view of this scenario,  the only option to detect renal failure in cats in time is to carry out periodic blood and urine tests in the animal,  from 8 years of age onwards.

In this way, better results can be obtained regarding the quality and life expectancy of the pussy.

Late and nonspecific signs indicating renal failure in domestic felines

Although the signs of kidney failure in cats may go unnoticed, or be confused with those of other illnesses, consult your veterinarian if your pet:

  • Show a progressive weight loss
  • lose your appetite
  • Drink more water than usual
  • urinate a lot
  • To vomit

In the final stages of the disease, the pet will be lethargic.

Treatment for a Pussy with Kidney Disease

An increase in urea and creatinine in the blood and a low density of urine are indicators of kidney failure. But if this insufficiency is not detected in time, chances are that the cat will have to be hospitalized to be hydrated.

Afterwards, he will have to follow a specific diet, with high quality proteins and a reduction in phosphorus and salt. Either way, the pet is likely not to accept the new food. In these cases, it is preferable to offer him some food that he likes. It is also possible to resort to the use of some substance that acts as a flavoring, so that he gets excited and recovers his appetite.

The veterinarian must also indicate a supplement that contains:

  • B group vitamins
  • Antioxidants
  • Potassium
  • Omega-3 fatty acids

Why does kidney failure in cats not show early signs?

The kidneys are made up of a large number of tiny tubes called nephrons, which are in charge of filtering and reabsorbing fluids. A healthy young cat has lots of nephrons. That’s why some are stored.

When kidney damage occurs, some nephrons stop working. At that moment, the ones that had been stored come into action  and none are left in reserve.

Then, as kidney failure progresses, and without back-up nephrons, the first signs of failure begin to become evident. The “nephron reserve” system is what masks the signs of disease until the damage really matters.

Causes of Kidney Failure in Pussies

But what makes the feline’s kidneys no longer able to properly filter and eliminate waste from the blood?

Unfortunately,  in most cases it is not possible to establish the specific reason for the kidney disease.  Biopsies usually show a large amount of fibrous tissue that replaces normal tissue, a fact that also occurs in other diseases.

Anyway, some causes can be:

  • polycystic kidneys
  • kidney tumors
  • infections
  • glomerulonephritis

Kidney failure in cats, a disease that must be detected early

Even though it is an irreversible disease,  the pussy can live with its kidney failure if the disease is detected early and receives the necessary care.

But if the diagnosis is late, even though not all animals react in the same way to treatment, the prognosis is usually not favorable.

Therefore, even if you make all the necessary efforts to keep the cat balanced and give it quality of life, it is likely that its health will continue to deteriorate and that it will die in a short time.
