How long can a cat go without eating before developing fatty liver?

According to veterinary literature, as little as 2-3 consecutive days of not eating can begin triggering hepatic lipidosis, especially in overweight cats. If your cat's appetite decreases for more than 48 hours for any reason, proactive intervention and veterinary consultation are recommended.

Do elevated liver enzymes always mean liver disease?

Elevated liver enzymes (ALT, AST, etc.) indicate hepatocellular damage but do not necessarily mean primary liver disease. Hyperthyroidism, diabetes, and certain medications can also cause abnormal liver values. Your veterinarian will interpret results in the context of other findings.
