Pet Jaundice Symptom Guide | Observation Points and When to Seek Care

Understand possible causes of Jaundice and key points for home observation

Jaundice may reflect abnormal liver, blood, or biliary function. If it spreads or worsens over a short time, take it seriously and act immediately.

Warning: Jaundice May Indicate Major Organ Dysfunction

Rapidly appearing or continuously spreading jaundice may indicate serious bilirubin metabolism or biliary obstruction problems, potentially causing systemic metabolic changes or complications and requiring priority care.

Recommended Action

If jaundice worsens rapidly within 24-48 hours, spreads, or occurs with obvious urine or stool color changes, go to a veterinary emergency service immediately.

What this symptom means clinically

Jaundice is yellow pigment deposition in tissues and mucous membranes, mainly caused by bilirubin accumulation in the body. Mechanisms include excessive prehepatic production from hemolysis, impaired hepatocellular uptake or metabolism, and biliary obstruction that blocks bilirubin excretion, causing discoloration of the skin, whites of the eyes, and mucous membranes.

🐱 In cats

In cats, jaundice is often related to liver disease or biliary problems. It may be more obvious in cats and can progress quickly.

🐶 In dogs

In dogs, jaundice may come from hemolytic disease, hepatocellular disease, or biliary obstruction, with more varied clinical signs and causes.

Clinical signs you can observe

Check whether your pet shows any of the signs below. If several apply, seek veterinary care promptly.

Check and photograph changes in yellowness of the whites of the eyes and gums with timing.
Observe and record whether the skin or inside of the ears appears yellow, comparing before-and-after photos.
Record the date jaundice first appeared and whether it worsened quickly when found.
Check and record whether urine becomes darker and when the change occurs.
Check and record whether stool becomes pale or abnormal, and photograph it for reference.
Record daily appetite and activity changes for veterinary evaluation.
