Why is my cat not eating? This is a question many cat owners ask when their furry friend suddenly refuses food. The reasons can range from something minor, like stress or a dislike of their current food, to more serious issues, such as dental problems, infections, or underlying health conditions.
If your cat is not eating food, pay attention to their behavior—are they drinking water, lethargic, or showing other symptoms? These clues can help you figure out what’s wrong.
If your cat refuses to eat for more than 24 hours, it’s important to take action. Start by checking for changes in their environment, like a new food brand or recent stressors.
If you notice other symptoms, like vomiting, lethargy, or dehydration, it’s time to consult your vet. Addressing the problem early can prevent further complications and ensure your cat stays healthy.
Common Reasons Your Cat Is Not Eating
A cat not eating food can be alarming, but it’s important to understand the potential reasons behind this behavior. Cats are sensitive creatures, and their appetite can be affected by various physical, emotional, and environmental factors. Here are some common reasons your cat refuses to eat and what each might mean.
Stress or Environmental Changes
Cats are creatures of habit, and changes in their environment can easily upset them. Moving to a new home, introducing a new pet, or even rearranging furniture can cause stress, leading to a cat suddenly not eating.
What to Do:
- Create a quiet, comfortable space for your cat to eat.
- Stick to a consistent feeding routine to reassure them.
Illness or Health Issues
A cat’s lack of appetite is often the first sign of an underlying health problem. Conditions like gastrointestinal issues, kidney disease, or infections can cause your cat to refuse to eat.
What to Do:
- Monitor for other symptoms, such as vomiting, diarrhea, or lethargy.
- If your cat not eating or drinking persists for more than 24 hours, contact your vet for a thorough examination.
Dental Problems
Cats with dental pain may avoid eating because it hurts to chew. This is especially common in older cats or those with gum disease.
What to Do:
- Check your cat’s mouth for signs of redness, swelling, or bad breath.
- Softening their food or switching to wet food can help temporarily, but consult a vet for a proper dental check-up.
Spoiled or Unfamiliar Food
Cats can be picky eaters. If their food has gone bad or they don’t like a new brand, they may simply avoid eating.
What to Do:
- Ensure the food is fresh and hasn’t expired.
- Gradually introduce new food by mixing it with their usual diet to help them adjust.
Aging or Behavior Changes
As cats age, their metabolism and eating habits can change. A senior cat not eating as much might have reduced energy needs or underlying health issues.
What to Do:
- Provide smaller, more frequent meals tailored to your cat’s age and activity level.
- Consult your vet for dietary recommendations suitable for senior cats.
Why Is My Cat Not Eating But Drinking Water?
If your cat is not eating food but drinking water, it’s a sign that something may be affecting their appetite while leaving their thirst intact.
This behavior can have several causes, ranging from mild digestive issues to more serious underlying health conditions. Understanding the potential reasons can help you determine the best course of action.
Digestive Discomfort or Upset Stomach
When a cat has a mild stomach upset, they may avoid food temporarily but still drink water to stay hydrated. This could happen if they’ve eaten something that didn’t agree with them or if they’re experiencing hairball-related discomfort.
What to Do:
- Observe their behavior for 24 hours. If the issue resolves on its own, it’s likely a minor upset.
- Offer easily digestible foods, like plain boiled chicken, to encourage them to eat.
Dehydration or Kidney Problems
If your cat not eating food but drinking water persists, it could indicate dehydration or early signs of kidney disease. Cats with kidney issues often drink more water to compensate for their body’s inability to retain fluids.
What to Do:
- Check for signs of dehydration by gently pinching the skin at the back of their neck—if it doesn’t snap back quickly, they may be dehydrated.
- Schedule a vet visit to rule out kidney problems or other medical conditions.
Dental Pain or Mouth Injury
Painful conditions like inflamed gums, broken teeth, or mouth ulcers can make eating uncomfortable for your cat, but they may still drink water since it’s less painful.
What to Do:
- Inspect their mouth for redness, swelling, or visible injuries.
- Switch to wet food or soak dry food in water to make it easier to eat, and consult your vet for dental treatment.
Stress or Anxiety
A stressed or anxious cat might lose interest in eating but still drink water. Common stressors include moving to a new home, loud noises, or changes in their environment.
What to Do:
- Minimize stress by providing a quiet, safe space for your cat to relax.
- Stick to a consistent routine to help them feel secure.
Underlying Illness
A cat not eating drinking could also be a sign of an underlying illness, such as liver disease, diabetes, or a respiratory infection affecting their sense of smell and appetite.
What to Do:
- Look for additional symptoms like vomiting, lethargy, or difficulty breathing.
- Contact your veterinarian immediately for a diagnosis and treatment plan.

My Cat Is Not Eating But Throwing Up Bile: What Does It Mean?
When your cat is not eating but throwing up bile, it’s a sign that something is wrong with their digestive system. Bile is a yellow or green fluid produced by the liver to aid digestion.
When a cat’s stomach is empty for too long, bile can irritate the stomach lining, leading to vomiting. This situation can be caused by minor issues like hunger or more serious health problems.
Empty Stomach or Hunger
If a cat goes too long without eating, bile can build up in their stomach, causing them to vomit. This is often seen when a cat skips meals or isn’t eating enough due to stress or changes in food.
What to Do:
- Offer small, frequent meals to prevent their stomach from staying empty for too long.
- Try feeding easily digestible foods like boiled chicken or plain rice to soothe their stomach.
Hairballs or Digestive Blockages
Cats groom themselves constantly, and hairballs are a common cause of vomiting. However, if your cat refuses to eat and continues to vomit bile, it could indicate a blockage in their digestive tract.
What to Do:
- Check for signs of constipation or difficulty passing stools.
- Use a hairball remedy or consult your vet for further evaluation if symptoms persist.
Gastritis or Stomach Inflammation
Gastritis, or irritation of the stomach lining, can cause a cat not eating food and vomiting bile. This can result from eating something toxic, ingesting non-food items, or even a sudden change in diet.
What to Do:
- Monitor your cat’s behavior and remove any potential hazards from their environment.
- Provide plenty of fresh water and consult your vet for treatment if the vomiting continues.
Pancreatitis or Liver Issues
When your cat is not eating or drinking and is vomiting bile, it could point to serious conditions like pancreatitis or liver disease. These conditions often come with other symptoms, such as lethargy or jaundice (yellowing of the skin or eyes).
What to Do:
- Look for signs of discomfort, such as hunching over or hiding.
- Schedule an urgent vet visit for a full examination and diagnosis.
Stress or Anxiety
Stress can lead to a cat suddenly not eating and vomiting bile due to an upset stomach. Changes in the environment, new pets, or loud noises can trigger this behavior.
What to Do:
- Create a calm, safe space for your cat to relax.
- Use calming aids, such as pheromone diffusers, to reduce their stress levels.
My Cat Is Lethargic and Not Eating: What Should I Do?
If your cat is lethargic and not eating, it’s a clear sign that something might be seriously wrong. Lethargy—when your cat is unusually tired, weak, or inactive—combined with a cat’s lack of appetite often points to underlying health issues. Here’s what you need to know and the steps you should take.
Common Causes of Lethargy and Appetite Loss
Several conditions can cause lethargy and a cat refusing to eat, including:
- Infections: Viral or bacterial infections, such as feline upper respiratory infections, can make your cat feel too weak to eat.
- Organ Problems: Issues like kidney disease, liver disease, or diabetes may cause a cat not eating as much and appearing lethargic.
- Pain or Injury: An injury or dental pain can reduce a cat’s activity and interest in food.
Signs That Require Immediate Attention
If your cat is not eating food and seems unusually tired, watch for these additional warning signs:
- Vomiting or diarrhea
- Difficulty breathing
- Signs of dehydration (e.g., dry gums, reduced skin elasticity)
- Sudden weight loss
What to Do:
- If your cat shows any of these symptoms, contact your vet immediately. Delaying treatment can worsen the condition.
How to Comfort Your Lethargic Cat
While you wait for professional advice or treatment, you can take steps to make your cat more comfortable:
- Create a Cozy Environment: Provide a quiet, warm, and soft space where your cat can rest.
- Encourage Drinking Water: A cat not eating or drinking can become dehydrated quickly, so ensure fresh water is always available.
- Offer Gentle Foods: Try tempting your cat with their favorite wet food or a bland option like boiled chicken to stimulate their appetite.
Potential Medical Treatments
If your vet diagnoses a specific condition, treatment may include:
- Medications: Antibiotics for infections or pain relievers for injuries.
- Fluids: For dehydration, your vet may provide subcutaneous or intravenous fluids.
- Special Diets: Prescription diets can help address organ-related issues or gastrointestinal problems.
When Should I Worry if My Cat Stops Eating?
It’s natural to be concerned when your cat suddenly stops eating, as even short periods of fasting can have serious consequences for their health.
While some cases of a cat not eating food are temporary and resolve on their own, others require immediate action. Here’s when you should start worrying and what steps to take.
How Long Can a Cat Go Without Eating?
Cats have sensitive metabolisms, and going without food for more than 24–48 hours can lead to serious complications, such as hepatic lipidosis (fatty liver disease). This condition is especially dangerous for overweight cats, as their bodies break down fat too quickly when they don’t eat.
What to Do:
- If your cat refuses to eat for more than a day, monitor their behavior closely for other symptoms like lethargy, vomiting, or dehydration.
- Offer highly palatable foods, such as wet food or warmed-up meals, to encourage eating.
Red Flags That Require Immediate Attention
If your cat not eating food but drinking water persists, or if they stop drinking as well, it’s time to consult a veterinarian. Look out for these signs:
- Weight loss
- Persistent vomiting or diarrhea
- Difficulty breathing or coughing
- Unusual hiding behavior
- Visible signs of pain or discomfort
These symptoms indicate a more serious issue that requires prompt medical attention.
Why Appetite Loss Is a Serious Concern
When a cat has no appetite, it’s often their body’s way of signaling that something is wrong. Common health issues linked to appetite loss include:
- Kidney or Liver Problems: Organ dysfunction can suppress hunger and lead to other symptoms like vomiting or lethargy.
- Infections: A respiratory infection can block a cat’s sense of smell, making food less appealing.
- Stress and Anxiety: Changes in the home, a new pet, or loud noises can lead to a cat refusing to eat.
When to Visit the Vet
You should schedule a vet visit if your cat:
- Hasn’t eaten for more than 24–48 hours.
- Shows additional symptoms like vomiting, diarrhea, or lethargy.
- Displays behavior changes, such as excessive hiding or aggression.
The vet may perform tests, including bloodwork or imaging, to identify the underlying cause and recommend appropriate treatment.
Prevention and Early Intervention
To avoid reaching this point, keep a close eye on your cat’s eating habits and overall health. If you notice your cat not eating as much, address it early by checking for potential stressors, experimenting with new foods, or consulting your vet for advice.
