Cats with Jaundice: Causes, Symptoms, and What You Should Do Immediately
Cats with jaundice often show visible changes that can alarm any pet owner. However, this condition is not a disease itself. Instead, it is a warning sign that something serious may be affecting your cat’s liver or blood system.
Jaundice, also known as icterus, causes a yellow discoloration in areas such as the eyes, skin, and gums. Therefore, recognising this early can help prevent more serious complications.
In this guide, you will learn the causes of jaundice in cats, common symptoms, and what steps to take immediately.
What Is Jaundice in Cats?
Jaundice occurs when there is an excess buildup of bilirubin in the blood. Normally, the liver processes bilirubin efficiently. However, when the liver is compromised, this process slows down.
As a result, bilirubin accumulates and causes the yellow appearance seen in cats with jaundice.

Common Causes of Cats with Jaundice
There are several underlying causes. Therefore, identifying the root problem is essential.
1. Liver Disease
Liver problems are one of the most common causes.
- Hepatitis
- Liver infections
- Liver damage
As the liver weakens, it cannot process toxins effectively.
2. Blood Disorders
Certain conditions affect red blood cells.
- Hemolytic anemia
- Blood parasites
As a result, red blood cells break down faster, increasing bilirubin levels.
3. Bile Duct Obstruction
Blockages can prevent bile from flowing properly.
- Gallstones
- Tumors
- Inflammation
Therefore, bilirubin builds up in the bloodstream.
4. Infections (Including FIP)
Infections such as FIP can affect liver function.
- Inflammation of organs
- Immune system disruption
As a result, cats with FIP may also develop jaundice.
Symptoms of Cats with Jaundice
Recognising symptoms early is critical.
Visible Signs
- Yellow eyes (most noticeable)
- Yellow gums
- Yellow skin (especially ears and belly)
Behavioural Changes
- Loss of appetite
- Lethargy
- Weight loss
Additional Symptoms
- Vomiting
- Dark urine
- Pale stool
Therefore, any combination of these signs requires immediate attention.

Why Jaundice Is Dangerous
Cats with jaundice may be experiencing serious internal issues.
If left untreated:
- Liver failure may occur
- Toxins build up in the body
- Overall condition worsens quickly
Therefore, early action can be life-saving.
What to Do If Your Cat Has Jaundice
If you notice jaundice symptoms:
1. Visit a Veterinarian Immediately
Early diagnosis is crucial.
- Blood tests
- Ultrasound
- Liver function tests
2. Identify the Underlying Cause
Treatment depends on the root issue.
- Liver support
- Infection control
- Medication
3. Support Your Cat at Home
While treatment is ongoing:
- Provide high-quality nutrition
- Ensure hydration
- Reduce stress
In addition, monitor your cat’s behaviour closely.
Jaundice in Cats with FIP
Cats with jaundice may also have FIP, especially in advanced cases.
FIP can:
- Affect liver function
- Cause inflammation
- Disrupt normal metabolism
Therefore, if jaundice appears alongside FIP symptoms, immediate treatment is critical.
Can Cats Recover from Jaundice?
Yes, recovery is possible.
However, it depends on:
- Early detection
- Correct diagnosis
- Proper treatment
As a result, many cats improve when treated early.
Final Thoughts on Cats with Jaundice
Cats with jaundice should never be ignored. Although the yellowing may seem like a simple symptom, it often indicates a deeper health issue.
In conclusion:
- Jaundice is a warning sign, not a disease
- Early action improves recovery chances
- Proper diagnosis is essential
Most importantly, acting quickly can make a significant difference in your cat’s health and survival.
