Glomerular Disease in Cats (July 2019)

Glomerular disease isn’t a common issue among cats, but it can be a deadly one when it does occur.

What is Glomerular Disease?

Glomerular disease has many names. It’s also known as glomerulopathy, glomerulonephritis, glomerulonephropathy, and protein losing nephropathy.

This type of disease is essentially chronic kidney disease in cats, so it’s very dangerous.

The kidneys of a cat contain millions of glomeruli, which help the kidneys do their job to filter things out properly.

If a cat has damaged kidneys, which means their glomeruli are damaged, larger protein molecules will be allowed to pass through their urine.

The Symptoms of Glomerular Disease

Glomerular disease doesn’t always show symptoms, but when it does, it’s usually because there is an underlying cause.

For example, an infectious bacterial disease, such as one from a tick, can present symptoms that relate to kidney disease.

Blood clot formation and high blood pressure are two symptoms that you will usually see when it comes to glomerular disease, whether it’s due to a problem with the kidneys alone or an underlying issue.

Cats with kidney diseases take awhile to show symptoms, but when they do, the following typically occurs:

  • Weight loss
  • Weakness
  • Lethargy
  • Vomiting
  • Loss of appetite
  • Increased thirst and urine production

If you spot any of the symptoms listed above, bring your cat to the vet as soon as possible.

The Causes of Glomerular Disease

There are a few ways glomerular disease occurs in cats:

  • Elevated blood pressure
  • Amyloidosis
  • Autoimmune inflammation
  • Glumerulosclerosis, which is a form of scarring

It’s important to know what causes this disease, even if you can’t actually see what’s causing it.

Talk to Your Vet

Knowing as much as you can about kidney conditions, as a whole, is a great way to stay informed and know what to look for. Regular checkups for kidney health will help, too!
