Common Causes

Stress, dental pain, hairballs, upper respiratory infection, dietary changes, or underlying illness. A cat that has not eaten in 24โ€“48 hours needs veterinary evaluation.

When It Is an Emergency

See a vet immediately if not eaten for 48+ hours, vomiting, lethargic, difficulty breathing, or is overweight (risk of fatty liver disease within 2โ€“3 days).

Home Remedies

Warm the food slightly to increase aroma. Try a different protein. Offer tuna water as an appetite stimulant. Make sure the bowl is clean and away from the litter box.

Gradual Food Transitions

Mix 25% new food with 75% old for 3 days, then 50/50 for 3 days, then 75/25 for 3 days. Sudden switches upset digestion.

Pro Tips

โœ“Cats should eat at least once every 24 hours
โœ“Stress-related appetite loss usually resolves in 1โ€“2 days
โœ“Multiple small meals may work better than one large meal
