Cats are famously picky eaters, often turning their noses up at food without warning. While a skipped meal may not be an immediate emergency, a cat not eating for an extended period can be a serious sign that something is wrong. As a responsible pet parent, it’s essential to know when to be concerned and how to take action quickly.
In this guide, we’ll explore the common reasons why your cat may stop eating, how long cats can go without food, and what you should do if you notice changes in their appetite. We’ll also share tips for encouraging eating and some good treats for cats that can help get their appetite back on track.
Why Is My Cat Not Eating?
There are many reasons why a cat may suddenly stop eating. Some are minor and easily resolved, while others require prompt veterinary care.
1. Medical Issues
Health problems are a leading cause of appetite loss in cats. Some of the most common include:
- Dental pain or oral infections: Tooth decay, gum disease, or abscesses can make eating painful.
- Kidney disease: Common in older cats, this condition can cause nausea and decreased appetite.
- Gastrointestinal problems: Vomiting, diarrhea, or constipation may discourage eating.
- Liver disease or pancreatitis
- Upper respiratory infections: If your cat can’t smell their food, they may not want to eat.
- Hyperthyroidism, cancer, or diabetes
If your cat is not eating and also shows signs of lethargy, vomiting, weight loss, or hiding behavior, consult a vet immediately.
2. Stress and Anxiety
Cats are creatures of habit. A move to a new home, the arrival of a new pet, loud noises, or changes in routine can all cause stress-induced appetite loss.
3. Changes in Food
Did you recently switch to a new brand or flavor of cat food? Cats can be sensitive to texture, smell, or taste changes. Even a slight alteration in the formulation can lead to rejection.
4. Vaccinations or Medications
Some medications or recent vaccinations can cause temporary nausea or digestive upset, leading to reduced appetite.
5. Hairballs or Obstruction
A hairball or something stuck in your cat’s digestive tract may reduce their desire to eat. If your cat hasn’t pooped in a while and seems uncomfortable, this could be a sign.
How Long Can Cats Go Without Food?
Unlike dogs or humans, cats cannot safely fast for long periods. A healthy adult cat can survive without food for around 24 to 48 hours, but beyond that, the risk of hepatic lipidosis—a potentially fatal liver condition—increases dramatically.
Kittens and senior cats are even more vulnerable. A kitten not eating for even 12 hours should be seen by a vet.
Water, however, is more critical. Cats can become dehydrated quickly, so if your cat isn’t eating or drinking for more than a day, that’s a red flag and requires prompt veterinary attention.
What to Do If Your Cat Isn’t Eating
1. Rule Out a Medical Emergency
If your cat refuses food for more than 24 hours or shows other signs of illness (vomiting, lethargy, drooling, weight loss), contact your vet immediately.
2. Offer Strong-Smelling, Tasty Foods
Cats rely heavily on their sense of smell. Try warming up wet food slightly or offering tuna water (not oil) to stimulate appetite.
3. Try Hand-Feeding
Sometimes, sitting down and gently hand-feeding your cat can make them feel more secure, especially if stress is the cause.
4. Check Their Environment
Look for stressors that may be affecting your cat. Has anything changed recently—like loud renovations, new pets, or people?
5. Switch to a Favorite or Prescription Diet
Reintroducing a favorite food or asking your vet for a highly palatable prescription diet can help jumpstart eating.
Good Treats for Cats to Encourage Eating
When your cat isn’t eating, offering treats can sometimes coax them into taking that first nibble and reset their appetite.
Here are some good treats for cats that are generally well-received:
- Churu lickable treats – High in moisture and great for hydration
- Freeze-dried chicken or salmon bites
- Boiled plain chicken or turkey
- Tuna or sardine in water (small amounts)
- Vet-approved treats for sensitive stomachs
Make sure treats are only a temporary measure and don’t replace a balanced diet. Use them to stimulate appetite or reward eating behavior.
Preventing Appetite Loss in Cats
While some appetite issues are unavoidable, you can take steps to reduce the risk:
- Keep a consistent feeding routine (same time and place)
- Avoid sudden changes in food
- Provide a stress-free environment
- Schedule regular vet checkups
- Keep water fresh and food dishes clean
When to Call the Vet
Contact your vet if:
- Your cat hasn’t eaten in 24+ hours
- They’re refusing both food and water
- There are signs of vomiting, diarrhea, or lethargy
- There’s weight loss or noticeable behavior change
- You suspect your cat ingested something toxic or has an obstruction
Prompt action can prevent a minor issue from becoming life-threatening.
FAQs
1. How long can cats go without food before it becomes dangerous?
A healthy cat should not go more than 24 to 48 hours without food. Beyond that, their liver may begin breaking down fat too quickly, leading to hepatic lipidosis, which is often fatal if untreated. If your cat isn’t eating, act quickly.
2. Can I give my cat treats to stimulate their appetite?
Yes, treats can be useful in encouraging your cat to eat. Offer good treats for cats like tuna flakes, freeze-dried meats, or lickable purees. Just be cautious not to overdo it or let them rely solely on treats.
3. What medical conditions cause cats to stop eating?
Dental issues, kidney disease, GI upset, liver problems, infections, cancer, and respiratory issues can all lead to appetite loss. A thorough exam by your vet will help identify the root cause.
4. My cat is still active but not eating—should I worry?
Yes. Even if your cat seems normal in energy but refuses food, it’s important to monitor closely. Lack of food for over 24 hours—even in an otherwise alert cat—can still be dangerous. Keep an eye on hydration and contact your vet if needed.
