Why Is My Cat Not Eating? A Cat Parent’s Complete Guide

vetsupply September 19, 2025 0 Comment

When your cat stops eating, you fret, and you wonder: Is this “just a phase”, or is something wrong? The answer is, it depends. Cats are picky eaters, and oftentimes you have to coax them into eating even their favourite meals. While this can be a short episode because of the “new flavour” that your cat isn’t a fan of, a prolonged inappetence in cats (anorexia) may point towards underlying problems. But don’t worry, there’s a lot you can do if your cat is suddenly not eating. In this blog post, we will go through why cats stop eating, when to worry, and how to help them get back to normal.

Possible Reasons Why Your Cat is Not Eating

Cats may stop eating if they are suffering from pain or discomfort due to a health problem. But that isn’t all. Stress, anxiety, and depression may also lead to loss of appetite in cats. Your cat food’s shape, texture, and aroma also play an important role in enticing them to eat. Here are some of the common reasons why your cat won’t eat.

Digestive issues

Problems related to the stomach, intestines, or any other digestive organs can affect your cat’s appetite. Some common illnesses that cause loss of appetite, especially when accompanied by symptoms like diarrhoea, gas, constipation, bloating, etc., include tumours, gastroenteritis, inflammatory bowel disease, and worm infestations.

Dental problems

Periodontal diseases, dental abscesses, teeth resorption, or gum inflammation can discourage cats from eating because of the dental pain associated with chewing. If you are wondering, ‘Why isn’t my cat eating?’, the most basic checkup that you can do at home is inspecting your cat’s teeth to rule out any such issues.

Respiratory problems:

Cats are gifted with a strong sense of smell, and most respiratory problems in cats lead to loss of smell or discomfort in swallowing, making eating unappealing to cats. If your cat is experiencing appetite loss along with symptoms like sneezing, coughing, wheezing, nasal discharge, rapid breathing, and weakness, consult your veterinarian promptly for diagnosis and treatment.

Stress & Anxiety

Cats are creatures of habit. If a cat won’t eat and is not suffering from any notable symptoms of a health problem, there is a high chance that she is not doing well emotionally. Any change, like a new home, a new pet, unfamiliar people, or a changed feeding spot or bowls, can unsettle them and lead to refusal of food.

Change of food/preference

A new flavour, texture, brand, or even just a new batch can turn cats off. So, if you have changed your cat’s food recently, probably your cat has rejected it. Cats may show a sudden disinterest in food even if you are serving the same food if the manufacturer has changed the ingredients/flavour without any obvious signs on the packaging. You may not easily pick up such tiny changes, but your cat can!

Ageing

As cats age, their metabolism changes and organ functioning slows down. They may need softer food, special kibble, or modified diets at this new life stage. They might start losing their sense of smell gradually, which causes refusal to eat. A senior cat’s reduced interest in food can be generally resolved by switching to an appropriate diet and bringing variety to their food.

Medications/medical treatments

After taking a vaccination shot or certain medications, cats may feel under the weather or nauseous. This can be temporary but still unsettling for them and may cause them to eat less than usual. Cats recovering from a surgical procedure may also face similar issues. Consult your vet if the hyporexia continues even after full recovery.

What to Do If Your Cat is Not Eating?

If your cat’s refusal to eat has occurred only once or twice, here are a few ways you can tempt them into eating again:

Make food smell tempting: Warm up your cat’s food a little to stir its aroma. Cats have strong olfactory senses, so even an easy step like this before serving their food can easily entice them to eat.
Switch textures/flavours gradually: If you are planning to switch your cat’s food type or flavour (say from dry to wet or from fish to chicken), transition gradually over a period of a week to avoid a sudden change.
Ensure a calm, clean feeding environment: Felines are cleanliness freaks and will hate if their food is placed near the litter area or in a noisy location. Provide clean bowls, fresh water, and a quiet place to ensure they eat well.
Offer small, frequent meals: Instead of one big portion, try splitting their meals into more frequent, smaller meals. This gives you more opportunities to feed and them more chances to eat.
Try something new for a change: Try serving a new cat food or something home-cooked, like plain chicken, fish, broth, or rice. These are not balanced options for long-term feeding, but they can help in the short-term to encourage eating.
Observe the signs closely: Note when the loss of appetite started. Was there a vet visit? New medicine? New food? New stressor? Also look for other signs like vomiting, diarrhoea, hiding, weight loss, lethargy, etc.
Consult the vet if needed: If it’s been more than a day or if you see any serious symptoms, don’t hesitate to visit a vet. The vet may recommend bloodwork or imaging, check dental health, or prescribe appetite stimulants.

Remember, these are not substitutes for vet advice — but in many cases, these small changes can help pull your kitty out of an anorexic state.

Can Your Cat’s Appetite Loss Lead to Something Serious?

Here’s the thing: cats don’t tolerate food deprivation like people do. If an adult cat refuses food for 24 hours, metabolism starts shifting. After 2–3 days, the risk of hepatic lipidosis (fatty liver disease) becomes very real. This is especially dangerous in overweight cats.

The health of kittens and senior cats can deteriorate faster. They have fewer reserves, so even shorter times can be risky. So yes, it’s OK to “wait a bit” if it’s just been one missed meal and nothing else is wrong. But if your cat is not eating for longer, it can be a sign of something serious.

When to See a Vet if Your Cat is Not Eating?

You must consult a veterinarian immediately if your cat is refusing to eat for over 24 hours (adult), or sooner in kittens or elderly cats. Also, look for other symptoms, such as vomiting, diarrhoea, dehydration, weight loss, bad breath, changes in urination, breathing difficulties, yellow gums or skin, sudden changes in behaviour, etc. Consult a vet straightaway if you notice any of these symptoms along with loss of appetite in cats. Don’t wait for things to get worse.

Prevention: Keeping Your Cat Eager to Eat

Preventing this scenario is always better than reacting when things are terrible. Here’s what you can do to keep your cat excited for meals:

Keep a consistent schedule for feeding, play, and rest, as cats love to follow a proper routine.
Keep rotating flavours and textures to keep them from getting overly bored of the same food.
Ensure regular dental checkups by a veterinary dentist. What looks like “just bad breath” could lead to a painful, serious issue.
Always make sure fresh water is available at all times. Dehydration may also lead to appetite drop.
Monitor your cat’s weight regularly. If your cat’s weight changes, it is important to adjust the feeding amounts accordingly.

Parting Words

Skipping one meal or two is just fine, but when it happens more frequently, constant monitoring and quick action are essential. If your cat is not eating, make a note of what could have changed. Is it the food, or routine, or health? Are there any other symptoms? If any red flags appear, don’t wait too long to visit a vet to catch any troubles early. With the right care and professional vet advice, you can help your cat bounce back with a healthy appetite quickly. And, sometimes, a meal served with an extra dash of love also works!
