It’s deeply concerning when your feline friend, usually so enthusiastic about mealtime, suddenly turns their nose up at their food bowl or water dish. As cat owners, we rely on their routines, and a change in eating or drinking habits can be a significant red flag. Cats are masters at masking discomfort or illness, so when they stop eating or drinking, it’s crucial to pay attention and understand the potential reasons behind this change. Determining whether it’s a minor, temporary issue or a sign of something more serious is key to ensuring your cat’s health and well-being.
Generally, a cat’s refusal to eat or drink, medically known as anorexia, can stem from three primary categories: an underlying medical condition, behavioral or emotional factors such as stress, or environmental changes. While skipping a meal occasionally might be normal for some cats, especially picky eaters, a prolonged period of not eating or drinking—specifically more than 24 hours—necessitates prompt veterinary attention. A veterinary professional can accurately diagnose the cause of your cat’s anorexia and recommend the appropriate treatment and care.

Decoding Why Your Cat Isn’t Eating: Common Causes of Feline Anorexia
Cats possess an instinctual ability to hide signs of illness, making it challenging to discern why they’ve stopped eating or drinking. The signs can range from obvious symptoms like vomiting to more subtle cues, such as simply refusing their meals for a day or two. If your cat has stopped eating or drinking, understanding the potential causes is the first step in getting them back to health.
Medical Reasons for Loss of Appetite in Cats
Various medical conditions can lead to a cat losing their appetite. It’s important to consider these possibilities when your cat is not eating.
- Digestive Issues: An upset stomach, nausea, or general gastrointestinal discomfort can significantly reduce a cat’s desire to eat. This can be caused by anything from mild indigestion to more serious conditions like gastritis or pancreatitis. Vomiting, diarrhea, or changes in stool consistency can accompany digestive upset.
- Dental Problems: Dental issues such as gingivitis, periodontitis, tooth resorption, or oral ulcers can make chewing painful and deter a cat from eating. Look for signs like drooling, pawing at the face, or bad breath.
- Pain: Pain from any part of the body, whether it’s arthritis, injuries, or post-surgical discomfort, can suppress a cat’s appetite. Cats often hide pain, so subtle changes in behavior, like decreased activity or reluctance to jump, might be the only indicators.
- Parasites: Internal parasites, such as worms, can cause various health issues, including appetite loss, especially in kittens and younger cats. Regular deworming is crucial for prevention.
- Infections: Infections, particularly upper respiratory infections (URIs), can affect a cat’s sense of smell and taste, leading to a decreased appetite. Fever, sneezing, nasal discharge, and lethargy are common symptoms of URIs.
- Food Allergies and Irritable Bowel Disease (IBD): Food allergies or intolerances, and conditions like IBD, can cause digestive upset and anorexia. Symptoms might include vomiting, diarrhea, itchy skin, and weight loss.
- Urinary Issues: Urinary tract infections (UTIs) or urinary stones can cause discomfort and pain, which can lead to a decrease in appetite. Straining to urinate, increased urination, or blood in the urine are signs of urinary problems.
- Toxin Ingestion: Ingesting toxic substances, such as certain household cleaners, plants, or medications, can cause severe illness and anorexia. Symptoms vary depending on the toxin but can include vomiting, tremors, seizures, and lethargy. Immediate veterinary care is critical if you suspect your cat has ingested something toxic.
- Foreign Body Ingestion: Cats sometimes ingest indigestible items like string, toys, or rubber bands, which can cause intestinal blockages. This is a serious condition that often leads to vomiting, lethargy, and a complete refusal to eat.
- Medication Side Effects: Certain medications can have side effects that include decreased appetite or nausea. If your cat has recently started a new medication and stopped eating, discuss this with your veterinarian.
- Underlying Systemic Diseases: Chronic conditions such as kidney disease, liver disease, diabetes, hyperthyroidism, and cancer are common causes of anorexia in cats, especially in older cats. These diseases often have subtle early symptoms, and loss of appetite can be one of the first signs.
It’s important to remember that while these medical reasons can sound alarming, a simple illness is often the most likely cause of a cat’s temporary loss of appetite. Just like humans, cats are less inclined to eat when they are feeling unwell, running a fever, or experiencing pain. However, it’s essential to rule out any serious underlying conditions, especially if the anorexia persists for more than 24 hours or is accompanied by other symptoms.

Behavioral and Emotional Factors Affecting Cat’s Appetite
Just like humans, a cat’s emotional state significantly impacts their appetite. Stress, anxiety, and fear are potent appetite suppressants in cats. Changes in their environment or routine, even seemingly minor ones to us, can trigger these emotional responses.
- Stress and Anxiety: New additions to the household, whether it’s a new baby, a new pet, or even houseguests, can be a significant source of stress for a cat. Moving to a new home, loud noises such as thunderstorms or construction, or changes in their daily routine can also induce anxiety. Even something as simple as altering the time or location of their feeding can upset a sensitive cat. Senior cats are particularly vulnerable to anxiety and behavioral issues and tend to be more sensitive to changes in their environment.
- Finicky Eating Habits: Some cats are naturally picky eaters. It’s not uncommon for them to skip a meal here and there, and this is usually not a cause for concern. However, if a picky eater refuses food for more than 24 hours, it’s essential to seek veterinary advice to rule out any underlying medical issues.
If your cat’s lack of appetite is due to stress or anxiety, they will typically resume eating once they have adjusted to the change. However, if stress and anxiety are chronic issues for your cat, behavioral modification techniques or medication might be necessary to help them cope. Consulting with your veterinarian is crucial to discuss these options and develop a strategy to manage your cat’s anxiety.

Environmental Changes That Can Stop a Cat from Eating or Drinking
Changes in a cat’s immediate environment, especially those related to their food and feeding routine, can also lead to anorexia.
- Dietary Changes: A recent change in your cat’s food can be a primary reason for food refusal. They might not like the taste, texture, or smell of the new food. Abrupt dietary changes can also cause gastrointestinal upset, further discouraging them from eating. When transitioning to a new cat food, it’s always recommended to do so gradually. Mix a small amount of the new food with their current food, gradually increasing the proportion of new food over 7-10 days to minimize digestive upset.
- Feeding Environment: In multi-pet households, mealtime competition or intimidation can be a significant stressor for some cats. Many cats feel stressed when they have to eat in close proximity to other animals, even if they are familiar housemates. This stress can lead them to avoid their food bowl altogether. Providing separate feeding areas for each pet, even if you have multiple cats, can significantly reduce mealtime stress and encourage better eating habits. Ensure each cat has a safe, quiet space to eat without feeling threatened or rushed.
Understanding Why Your Cat Might Stop Drinking Water
While it’s less common for cats to stop drinking than to stop eating, a decrease in water intake is a serious concern and requires immediate veterinary attention. Dehydration can quickly become life-threatening for cats, affecting organ function and overall health.
Common Reasons for Decreased Water Intake in Cats
- High-Moisture Food: If you’ve recently switched your cat to a diet that includes canned food or other high-moisture options, you might notice them drinking less water. This is perfectly normal because they are getting a significant portion of their hydration from their food. Canned food, in particular, has a much higher water content than dry kibble. As long as your cat is eating well and seems otherwise healthy, a decrease in water intake when on a high-moisture diet is usually not a cause for alarm. However, it’s still important to monitor their overall health and eating habits.
When Increased Thirst and Loss of Appetite Are Red Flags
- Underlying Health Problems: Paradoxically, sometimes a cat that is not eating may also be drinking more water than usual. This combination of increased thirst (polydipsia) and decreased appetite or anorexia can be a significant indicator of underlying health issues such as diabetes or kidney disease. Both of these conditions can cause increased thirst as the body tries to compensate for imbalances. If you notice your cat is drinking excessively and simultaneously has lost their appetite, it’s crucial to schedule a veterinary appointment immediately. These conditions require prompt diagnosis and management to prevent serious complications.

What to Do When Your Cat Refuses to Eat or Drink: A Step-by-Step Guide
If your cat has stopped eating or drinking, the most important action is not to wait to see if their appetite improves spontaneously. Prolonged anorexia in cats, even for just a day or two, can put them at risk of developing a severe condition called hepatic lipidosis, or fatty liver disease. This condition is particularly dangerous for obese or overweight cats, but it can affect cats of any weight. Hepatic lipidosis occurs when the body starts breaking down fat reserves for energy due to lack of food intake, overwhelming the liver.
If you notice your cat has stopped eating or drinking, contacting your veterinarian is crucial. Many veterinary practices offer virtual consultation services, which can be a helpful first step. A virtual consultation allows you to discuss your cat’s symptoms and receive initial guidance from a veterinary professional from home. They can help you assess the situation, provide advice on home care, and determine if an in-person examination is necessary.
When is a Cat Not Eating or Drinking an Emergency?
Certain situations require immediate veterinary care when a cat is not eating or drinking:
- Kittens: Young kittens are especially vulnerable because they have limited energy reserves. Their blood sugar levels can drop dangerously quickly if they don’t eat, leading to serious consequences like seizures.
- Senior Cats: Older cats are more prone to underlying health conditions. Anorexia in a senior cat is more likely to be indicative of a serious underlying issue that requires prompt diagnosis and treatment.
- Underweight Cats or Cats with Existing Health Problems: Cats that are already underweight or have pre-existing health conditions are less resilient and more susceptible to complications from not eating or drinking.
- Signs of Illness: If anorexia is accompanied by other signs of illness such as vomiting, lethargy, weakness, fever, diarrhea, or changes in urination, it’s crucial to seek immediate veterinary care.
- Weight Loss: Noticeable weight loss in conjunction with anorexia is a significant red flag and warrants immediate veterinary attention.
- Suspected Toxin or Foreign Body Ingestion: If you suspect your cat has eaten something toxic or swallowed a foreign object, this is an emergency situation requiring immediate veterinary intervention.
In any of these scenarios, do not delay in seeking veterinary care. Prompt action can significantly improve your cat’s prognosis and prevent serious complications.
Veterinary Diagnosis and Treatment for Cats Not Eating or Drinking
The cornerstone of treating a cat who is not eating or drinking is identifying and addressing the underlying cause, along with providing supportive care to stabilize the cat and prevent complications.
Diagnostic Tests Your Vet May Perform
To determine why your cat isn’t eating or drinking, your veterinarian will start with a thorough physical examination and ask you detailed questions about your cat’s symptoms, behavior, environment, diet, and any recent changes in their routine. Based on this initial assessment, they may recommend various diagnostic tests to pinpoint the underlying issue.
- Fecal Test: A fecal examination is crucial to check for intestinal parasites, which are a common cause of illness, especially in younger cats.
- Bloodwork and Urinalysis: These are routine but essential diagnostic tests. Bloodwork can evaluate organ function (liver, kidneys), check for infection, assess blood sugar levels (to rule out diabetes), and provide a general overview of your cat’s health status. Urinalysis helps assess kidney function and detect urinary tract infections or other urinary issues.
- X-rays or Ultrasound: Imaging techniques such as X-rays or ultrasound can help visualize internal organs and detect foreign bodies, tumors, or other abnormalities that might be causing the anorexia. They are particularly useful in cases where a gastrointestinal blockage or organ enlargement is suspected.
- Infectious Disease Tests: Depending on your cat’s symptoms and risk factors, your veterinarian might recommend tests for infectious diseases such as Feline Leukemia Virus (FeLV) or Feline Immunodeficiency Virus (FIV), especially if they are showing signs of fever, lethargy, or other systemic illness.
In some cases, depending on the initial findings, your veterinarian may recommend more specialized tests such as biopsies to further investigate specific conditions.

Treatment Approaches and Supportive Care
Once a diagnosis is established, your veterinarian will develop a targeted treatment plan to address the underlying cause of your cat’s anorexia. This treatment will be specific to the diagnosed condition. For instance, a cat with a dental infection will require dental treatment, while a cat diagnosed with diabetes will need insulin therapy and dietary management. If stress or anxiety is the primary factor, the treatment plan may include behavioral modification strategies or anti-anxiety medication.
Regardless of the underlying cause, supportive care is a critical component of treatment. Supportive care aims to help your cat feel better, prevent complications from not eating (such as dehydration and nutrient deficiencies), and promote recovery. Common supportive treatments include:
- Anti-nausea Medications: To alleviate nausea and vomiting, which can deter eating.
- Antacids or Stomach Protectants: To reduce stomach acid and protect the stomach lining, especially if digestive upset is suspected.
- Appetite Stimulants: Medications specifically designed to stimulate appetite can be used to encourage a cat to start eating again.
- Pain Medications: If pain is a contributing factor, pain relief medication is essential to improve comfort and encourage eating.
- Fluid Therapy: Dehydration is a common complication of anorexia, especially if the cat is also not drinking or is vomiting. Fluid therapy, administered intravenously or subcutaneously, helps rehydrate the cat and maintain electrolyte balance.
- Special Diets: Highly palatable and easily digestible prescription diets may be recommended to tempt a sick cat to eat and provide necessary nutrients. In some cases, assisted feeding, such as syringe feeding, may be necessary to ensure adequate nutritional intake until the cat’s appetite returns.
Your veterinarian may also suggest strategies to make food more appealing to your cat, such as offering canned food, warming the food to enhance its aroma, or offering favorite treats to entice them to eat.
Important Reminder: Never administer human medications to your cat without explicit direction from your veterinarian. Many human medications are toxic to cats and can be life-threatening.
If picky eating habits are identified as the primary issue, your veterinarian can provide guidance and strategies to establish a healthy eating routine and ensure your cat receives a balanced diet.
Whether the reason for your cat’s anorexia is medical, behavioral, or environmental, prompt veterinary consultation is crucial. With timely diagnosis and appropriate treatment, your veterinary team can help get your cat back to their happy, healthy, and hungry self in no time. Don’t hesitate to reach out to your veterinarian at the first sign of anorexia – early intervention is key to the best possible outcome.
