Yellow gums, ears or eyes in cats
Yellow gums, ear skin or whites of the eyes can indicate jaundice caused by bilirubin accumulation. It is not a normal coat-colour change and requires same-day veterinary assessment.

Yellow gums, ears or eyes in cats — the quick answer
✓ Contact a veterinarian the same day and keep the cat eating only as professionally advised.
✓ Weakness, collapse, breathing trouble, pale gums, repeated vomiting or toxin exposure is an emergency.
✓ This information supports observation and does not replace veterinary diagnosis.
Check natural light for yellow color in gums, ear skin and the whites of the eyes, plus urine and appetite. This guide explains what to record, what not to do and when veterinary care becomes urgent.
Confirm the colour in more than one area
Look in natural light at unpigmented gum tissue, the inner ear flap and the whites of the eyes without forcing handling. Compare both sides and take one clear photograph if easy. Warm indoor bulbs, cream fur and camera filters can create a yellow cast, but visible yellow tissue should not be watched for days.
Record the complete illness pattern
Note appetite, weight, vomiting, diarrhoea, energy, fever-like behaviour, abdominal enlargement, urine colour and stool colour. List every medicine, supplement, flea product, plant or possible toxin exposure. Bring packaging when relevant rather than relying on the colour to identify a liver problem.
Understand that jaundice is a sign
Bilirubin can rise when red blood cells are destroyed, when the liver cannot process it normally or when bile flow is obstructed. These categories need different investigation and treatment. Yellow gums do not prove one specific disease, and a home liver supplement cannot determine or correct the cause.
Arrange assessment the same day
Contact a veterinarian promptly even when the cat remains alert. Cats that stop eating can develop serious secondary liver complications, so report actual intake and how long it has changed. Do not force-feed or abruptly change diet unless the veterinary team gives an individual plan.
Escalate combined warning signs
Seek emergency care for marked weakness, collapse, breathing difficulty, repeated vomiting, inability to keep water down, severe pain, pale gums, bleeding, seizures or possible toxin exposure. Keep handling gentle and transport in a ventilated carrier. Do not delay to obtain urine or stool samples.
Follow testing and nutrition instructions precisely
The veterinarian may use blood and urine tests, imaging and other investigations to distinguish red-cell, liver and bile-duct causes. Give only prescribed treatment and follow the feeding plan exactly. Return promptly for worsening yellow colour, reduced intake, vomiting, confusion or bleeding.

A broken cat tooth may expose sensitive tissue or hide damage below the gumline even when the cat still eats. Prevent hard chewing, do not test or file the tooth and arrange a veterinary dental assessment; facial trauma, jaw misalignment or heavy bleeding is urgent.
