It can be incredibly worrying when your feline friend suddenly loses their appetite or you come across a stray cat that appears to have missed several meals. As dedicated cat owners, understanding their needs is paramount, especially when it comes to basic necessities like food and water.
So, how long can a cat realistically go without food, and more crucially, without water? To provide you with accurate and expert-backed information, we consulted with veterinary professionals, Dr. Michelle Burch from Paramount Pet Health, and Dr. Claudine Sievert from Stayyy, to clarify the critical timelines and how to encourage your cat to eat and drink again.
Understanding Cat’s Survival Without Food
While cats are resilient creatures, prolonged periods without food can be severely detrimental to their health. Generally, a healthy cat can survive for approximately two weeks without food if they have access to water. However, this is a maximum timeframe, and their condition will deteriorate significantly within this period. Realistically, even with water, a cat might only survive for three to four days without food before serious health complications arise.
Dr. Claudine Sievert emphasizes the rapid onset of health issues: “It’s crucial to understand that if a cat abstains from food for just two days, they will quickly become malnourished and visibly unwell.”
Unlike dogs and humans, a cat’s liver is uniquely susceptible to starvation. When a cat doesn’t eat, their body starts breaking down fat reserves for energy. This process, in cats, can overwhelm the liver, leading to a dangerous condition called hepatic lipidosis, or fatty liver disease. If not promptly treated, hepatic lipidosis can be fatal.
Dr. Sievert further explains this critical difference: “A cat’s liver is not equipped to handle starvation like other species. The process of liver damage can begin very quickly. If food deprivation continues, organ failure will inevitably follow.”

The Critical Need for Water: Cat Dehydration
Water is even more critical for a cat’s survival than food. It plays a vital role in virtually every bodily function.
Dr. Sievert explains the extensive role of water: “Water is absolutely essential for a cat’s physiology. It ensures cellular function, supporting all organ systems. It is crucial for brain health, blood circulation, metabolism, digestion, preventing constipation, flushing out toxins through urine, and maintaining a balanced pH level.”
Given water’s crucial functions, the survival window without it is significantly shorter. A cat can typically only survive for three to four days without water.
Dr. Michelle Burch warns about the rapid onset of dehydration: “Dehydration can begin in as little as 24 hours if a cat stops drinking. As water deprivation continues, dehydration worsens, leading to electrolyte imbalances and potential organ damage.”

Why is Your Cat Not Eating or Drinking? Common Causes
If your cat has suddenly stopped eating or drinking, it’s essential to identify the underlying cause. There are numerous reasons why this might occur, ranging from minor issues to serious medical conditions.
Some of the most frequent reasons for appetite and thirst loss in cats include:
- Digestive Upset: A simple upset stomach can temporarily deter a cat from eating.
- Dietary Changes: Abrupt changes in food can be stressful for cats and lead to temporary food refusal.
- Stress and Emotional Factors: Stressful events like a change in environment or owner absence can affect a cat’s appetite.
- Dental Problems: Tooth pain or gum disease can make eating uncomfortable or painful.
- Medication Side Effects: Certain medications can cause nausea or appetite suppression.
- Parasitic Infections: Internal parasites can sometimes lead to a loss of appetite.
- Inflammatory Bowel Disease (IBD) and Digestive Issues: Conditions affecting the digestive system can cause discomfort and reduce appetite.
- Underlying Medical Conditions: Various illnesses can manifest as a loss of appetite or thirst.
The extensive list of potential causes underscores the importance of seeking veterinary advice.
Dr. Burch advises prompt action: “If your cat has not eaten for more than 24 hours, a veterinary consultation is strongly recommended. Identifying the reason for their refusal to eat and establishing a treatment plan is critical. The longer a cat goes without food, the greater the risk of developing secondary liver disease.”
Encouraging Your Cat to Eat and Drink: Practical Steps
While waiting for a vet appointment or in the initial 24 hours of noticing your cat’s reduced appetite, there are several strategies you can try to encourage them to eat and drink.
1. Prioritize Hydration
Ensuring your cat stays hydrated is the immediate priority. Dehydration can complicate recovery and exacerbate existing health issues.
Dr. Burch suggests ways to boost water intake: “If your cat is not drinking adequately, try adding a small amount of low-sodium chicken broth or tuna juice to their water to make it more appealing. If this doesn’t work, you can try syringe-feeding small amounts of water or an electrolyte solution like Pedialyte every couple of hours.”
2. Tempt with Palatable Food Options
Next, try enticing your cat with different food choices, especially if they are usually fed dry kibble.
Dr. Burch recommends: “Offer a bland diet of easily digestible foods like boiled chicken, white rice with plain yogurt, or meat-flavored baby food. Changing the food’s flavor and texture can sometimes be enough to stimulate their appetite.”
Dr. Sievert adds that warming the food slightly can also make it more appealing, as cats often prefer food that is at room temperature or slightly warm.
3. Create a Calm and Clean Feeding Environment
Cats are sensitive to their surroundings. Ensure their feeding area is quiet and peaceful, away from loud noises or disturbances. Clean food and water bowls are also essential. Cats can be particular about hygiene and may avoid eating or drinking from dirty bowls.
In conclusion, while cats can technically survive for up to two weeks without food and a few days without water, these limits are far from ideal and put your pet at severe health risk. Any instance of a cat refusing food or water should be taken seriously. Prompt veterinary attention is crucial to diagnose and address the underlying issue, ensuring your feline companion stays healthy and happy. Do not hesitate to seek professional help if you notice changes in your cat’s eating or drinking habits.
