Jaundice reflects abnormal bilirubin handling and typically appears first on inner ear skin, gums, and eye whites, hidden elsewhere under fur.

Causes include hepatic lipidosis, cholangiohepatitis, and hemolytic anemia, most of which progress quickly, making yellowing a same-day vet signal rather than a watch item.

Check inner ears and gums in daylight; light-coated cats are easier to read, and deep orange-brown urine is a supporting clue.

Jaundice often comes with total anorexia and depression, so note recent intake and medications for the visit; treatment depends entirely on veterinary diagnosis.
