Cat Not Eating: Why It's Serious & What to Do
Don't wait it out. Cats that stop eating for more than 24 to 48 hours can develop hepatic lipidosis (fatty liver disease), which is life-threatening. Overweight cats are at highest risk.
Common causes
- Dental pain
- Stress — moving, new pets, changes in routine
- Nausea from kidney disease, liver disease or pancreatitis
- Upper respiratory infection (a blocked nose means they can't smell food)
- Food change or dislike
- Blockages from swallowed objects
See a vet if
- Your cat hasn't eaten in 24 hours (sooner for kittens)
- There's vomiting, drooling, hiding or weakness
- Your cat is straining in the litter box or can't urinate (emergency, especially in males)
- Yellow tint to the gums, ears or eyes
What you can try in the meantime
- Warm wet food slightly to boost the smell
- Offer a familiar food in a quiet spot
- Keep fresh water nearby
- Never force-feed without vet guidance
