My Kitten Not Eating

A kitten that will not eat can become seriously ill fast, especially if very young or also weak, vomiting, or dehydrated. Here’s how to tell when this is an emergency, what to do right now, and when your kitten needs a vet immediately.

Emergency

This can be a veterinary emergency.

If your kitten is not eating and is very young, lethargic, vomiting, having diarrhea, struggling to breathe, or seems weak or dehydrated, call a veterinarian right away or go to an emergency animal hospital.

When to call a vet

Emergency

Go to the ER now

  • Your kitten is younger than 6 weeks and has avoided food for 12 hours or less.
  • Your kitten has not eaten for 24 hours.
  • Your kitten is weak, collapsed, hard to wake, or unusually sleepy.
  • There is vomiting, diarrhea, trouble breathing, pale gums, seizures, or collapse.
  • Your kitten may be dehydrated, feels cold, or is not drinking.
  • Your kitten may have eaten a toxin, string, ribbon, foreign object, or spoiled food.
Urgent

See a vet within 24 hours

  • Your kitten is eating much less than normal for a day, even if still drinking.
  • There are signs of mouth pain, drooling, bad breath, or trouble chewing or swallowing.
  • There is nasal congestion, eye discharge, sneezing, or fever along with poor appetite.
  • Your kitten seems hungry but approaches food and cannot eat normally.
Monitor

Watch at home, call if it worsens

  • Your kitten misses part of one meal but is otherwise bright, playful, drinking, and quickly returns to normal eating.
  • A mild appetite dip happened during a recent food transition or stressful change, but your kitten is acting normal and improves promptly.

What Happened & Why It's Dangerous

🪫

Young kittens have little reserve

Very young kittens can become dangerously weak if they stop eating, and kittens under 6 weeks may be at risk after only about 12 hours without food.

🔍

Not eating is a symptom, not a diagnosis

Loss of appetite can happen with infections, parasites, fever, gastrointestinal disease, dehydration, pain, congenital problems, and many other illnesses.

👄

Some kittens want to eat but cannot

Mouth pain, ulcers, dental problems, trouble swallowing, or severe nasal congestion can make a kitten approach food but fail to chew or swallow it.

🫁

Ongoing poor intake can lead to serious complications

Cats that do not eat are at risk of worsening dehydration and other complications, and veterinary care is needed to find and treat the underlying cause.

What to Do Right Now

Call a veterinarian promptly — If your kitten is very young, has not eaten for many hours, or has any other symptoms, contact your vet or an emergency clinic now.

Check for other warning signs — Look for vomiting, diarrhea, trouble breathing, hiding, weakness, pale gums, eye or nose discharge, drooling, belly pain, or signs of dehydration.

Offer fresh food and water — Offer their normal kitten food, a clean bowl, and a quiet place to eat. Do not force-feed unless a veterinarian specifically tells you how.

Do not give human medications — Do not give over-the-counter medicines, appetite stimulants, or home remedies unless your veterinarian recommends them.

If toxin or object exposure is possible, say so immediately — Tell the veterinary team if your kitten may have chewed string, ribbon, plants, human food, chemicals, or anything that could cause poisoning or blockage.

  • Call a veterinarian promptly
  • Check for other warning signs

Common questions

How long can a kitten go without eating?
Not long. Very young kittens can become critically ill much faster than adult cats. Cornell notes that kittens younger than 6 weeks may face a life-threatening risk after about 12 hours without food. Any kitten that has not eaten for 24 hours needs immediate veterinary attention.
Why would a kitten stop eating?
Common reasons include upper respiratory infection, fever, parasites, stomach or intestinal disease, dehydration, mouth pain, dental or oral ulcers, stress, congenital illness, and toxin or foreign-body exposure. A kitten may also seem hungry but be unable to chew or swallow normally.
What symptoms make this an emergency?
Go urgently if your kitten is weak, cold, dehydrated, vomiting, has diarrhea, trouble breathing, pale gums, collapse, seizures, or has not eaten for 24 hours. If the kitten is under 6 weeks old, loss of appetite is urgent much sooner.
Should I syringe-feed my kitten at home?
Not unless your veterinarian tells you to. Force-feeding can increase stress and may raise the risk of aspiration, where food goes into the airway instead of the stomach. Call your vet for guidance first.
