Jaundice in Cats: Signs, Causes, and When to See a Vet

Introduction

If you’ve noticed a yellowish tint in your cat’s eyes, gums, or ears, it could be a sign of jaundice, also known as icterus. This condition is not a disease but a symptom of an underlying health issue requiring veterinary attention. This article will explore the signs of jaundice in cats, the common causes, and when to take your feline friend to the vet.

What Is Jaundice in Cats?

Jaundice develops when bilirubin, a yellow-colored substance formed from the breakdown of red blood cells, builds up excessively in the bloodstream and body tissues. This can happen if your cat’s liver isn't working efficiently or if red blood cells are being destroyed too rapidly, leading to visible yellowing of the skin, eyes, and gums.

How to Recognize Jaundice in Cats

The most visible sign of jaundice is yellow discoloration. Here are the areas where it’s easiest to spot:

  • Eyes: The whites of the eyes (sclera) may appear yellow.
  • Gums and Mouth: Gums may have a pale yellow tint instead of normal pink.
  • Ears and Skin: The ears and areas with less fur may appear yellow.
  • Urine Color: Urine may be dark or orange-brown.
  • Lethargy and Loss of Appetite: Cats may appear weak or uninterested in food.
  • Weight Loss: Rapid or unexplained weight loss can occur if the underlying condition is severe.

If you see any of these signs, it’s important not to wait. Early detection can significantly affect your cat’s recovery.

Common Causes of Jaundice in Cats

There are three main types of jaundice in cats, depending on where the problem originates:

1. Pre-Hepatic (Before the Liver)

This form is usually due to the destruction of red blood cells faster than the liver can process. Common causes include:

  • Blood parasites like Mycoplasma haemofelis
  • Autoimmune hemolytic anemia
  • Certain toxins or medications

2. Hepatic (Within the Liver)

When diseased or damaged, the liver fails to process bilirubin effectively. Possible causes include:

  • Hepatitis or liver infections
  • Liver cancer
  • Fatty liver disease (hepatic lipidosis), especially in overweight cats who stop eating
  • Feline infectious peritonitis (FIP)

3. Post-hepatic (After the Liver)

Blockages that prevent bile from leaving the liver can lead to jaundice. These may result from:

  • Gallbladder disease
  • Pancreatitis
  • Tumors obstructing the bile duct

Diagnosing Jaundice in Cats

If jaundice is suspected, your vet will conduct a comprehensive physical examination and recommend specific diagnostic tests to determine the underlying cause. These may include:

  • Blood tests help evaluate liver performance and identify potential infections or signs of anemia.
  • Urinalysis: Helps evaluate how well the liver is processing waste.
  • X-rays or Ultrasound: To visualize liver size, shape, and blockages or tumors.
  • Biopsy: In certain situations, a liver biopsy might be required to confirm the exact cause of the condition.

Treatment Options

Treatment depends on the underlying cause. Your vet may recommend:

  • Hospital stay may be necessary to provide supportive treatments like intravenous fluids, medications to control nausea, and essential nutritional therapy.
  • Antibiotics or Antivirals: If an infection is detected.
  • Steroids or Immunosuppressants: In cases of autoimmune disease.
  • Surgery: To remove blockages or tumors if necessary.
  • Dietary Changes: Prescription diets may be recommended to support liver health.

Prompt and appropriate treatment can lead to full recovery, especially when jaundice is caught early.

When to Visit the Vet

Don’t wait for the symptoms to worsen. Seek immediate veterinary care if your cat:

These symptoms could point to a serious health issue that requires immediate veterinary care.

Can Jaundice Be Prevented?

While not all causes of jaundice are preventable, you can reduce your cat’s risk by:

  • Keeping their vaccinations up to date
  • Feeding a balanced and nutritious diet
  • Scheduling regular vet check-ups
  • Preventing obesity, which can lead to fatty liver disease
  • Avoiding exposure to toxic plants and harmful medications

Final Thoughts

Jaundice in cats is a warning sign of something more serious happening inside the body. Early detection and treatment are crucial, whether it's a liver issue, infection, or blood disorder. If you notice any yellowing or unusual behavior in your cat, don’t delay—contact your veterinarian right away. With the proper care, many cats can recover and enjoy a healthy life.

Two sweet girlies decided to make our deck their home. Mosquitoes are a big problem where we live and we had to get them protected. This was the best bang for the buck. I’ve ordered from 79Pets several times and while delivery is not fast it is very consistent.

After Seresto collars failed to get rid of fleas, I didn't know where to turn. I saw a post on a page I follow (Kentucky Kitty Cats) saying that they use Nexgard Combo for the cats they shelter. I decided to try it and IT WORKS!

Last year, I made a visit to the vet. I told them that Kattie/cat had ear mites. They gave me an ointment costing $80canadian. I used it up and purchased another bottle. $160. total not including the cost of the vet visit. No results. The ear mites have been there for a long time. Canadian vets have control of what is sold in Pet stores and you cannot purchase off the shelf products not recognized by them. I jumped at the chance to purchase your produce with a recommended 100% effectivity. I was willing to try, but was suspicions. After a month there was still a little scratching but after 6 weeks, the mites are gone and the scratching is gone. Thank you very much for this mite solution. I recommend it heartily. Harry P.S. Do not tell the Canadian vets as they will outlaw your product.
