How Long Can A Cat Go Without Food And Water Before Dying?

If you are asking the question, “How long can a cat go without food and water?” this is likely because there has been a significant change in your cat’s appetite; or your cat has completely stopped eating.

Like humans, cats can survive longer without eating than they can without drinking. On average, cats can survive up to two weeks without food but can only go three days without water. Though this is the case, your cat can develop serious and life-threatening health problems the longer he or she goes without food.

If you are noticing a change in your cat’s eating habits, you have a right to be concerned. To best help your cat, you need to learn what can cause a cat not to eat as well and how long a cat can go without food.

Reasons Cats Refuse to Eat


Will A Cat Starve Itself To Death

The reasons cats will not eat are numerous. The most common reasons cats refuse food are sickness, boredom with the food, pain when eating, vaccination and medication side effects and stress. Let’s explore each of these reasons in detail as well as how to remedy such situations.


The most common reason cats refuse to eat is due to illness. When cats are ill, they feel unwell, thus they lose their appetites. Other problems that are usually present when a cat is ill are lethargy, fever and nausea.

Sometimes, cats will experience pain when they are ill, especially if an infection is present. Respiratory infections will especially make cats lose their appetite because these types of infections make cats feel unwell, and they can also prevent cats from being able to smell their food.

Cats use their sense of smell to see if foods are safe to eat. When cats smell their food, they are checking to see if the food is spoiled or is poisonous. When cats are unable to smell, they are uncertain whether the food is safe to consume, so they refuse to eat because of distrust.

Intestinal problems can also cause cats to lose their appetites. Common intestinal ailments that interfere with eating are inflammatory bowel disease, irritable bowel syndrome, colitis, viruses, parasitic infections, constipation, gastritis, ulcers, and cancer of the digestive tract.

What to Do When a Sick Cat Will Not Eat?

What to Do When a Sick Cat Will Not Eat

When sick cats refuse to eat, it is best to get medical attention. Resolving or treating the illness is key to get cats to eat again. Of course, there may be appetite difficulties during the recovery process or during the time it takes to find the proper treatment for a long-term illness.

How Can I Get My Cat’s Appetite Back?

While going through the recovery process or when trying to find the proper treatment for a long-term illness, cats may struggle with appetite difficulties. If this is the case for your cat, there are certain foods you can feed your cat that may provide appetite stimulation. These foods are as follows:

  • Wet cat food
  • Turkey baby food
  • Chicken baby food

Whether you feed your cat baby food or wet cat food, make sure to heat it up as heating the food will bring out the aromas more. Also, when you feed baby food, make sure there are no other ingredients besides the plain meat as seasonings are toxic to cats.

Boredom with the Food

Sometimes, cats stop eating when they get bored with their food. This often happens when cats eat the same food repeatedly, and they grow tired of it. Just like humans, cats can grow tired of eating the same food all the time.

Contending with Boredom

If you sense that your cat is bored with his or her food, you need to make things interesting. You can do this by offering a wide variety of foods or even toppings to see what will grab your cat’s attention. When you find foods that your cat likes, continue offering them.

If you want to prevent your cat from becoming bored with food in the future, change your food offerings at mealtimes. For example, you can offer your cat meat to eat for one meal, and you can offer salmon for another.

Pain When Eating

Pain is another reason cats will refuse to eat. Cats will experience pain when eating because of mouth sores, gum inflammation, gum disease, and gum infections.

Resolving the Pain

Once you treat the underlying cause for your cat’s pain, your cat will begin eating again. In most cases, antibiotics and medications for inflammation will solve problems with the mouth, teeth and gums. In more severe cases, surgery will be required.

Vaccination and Medication Side Effects

Medications and vaccinations can sometimes cause cats to lose their appetites. Some common medication and vaccination side effects that can interfere with eating are loss of appetite, nausea, and lethargy

Often, cats will begin to feel better within a day. Just in case it takes longer for side effects to go away, medications can be prescribed to mitigate these side effects so cats will feel comfortable enough to eat. If your cat is experiencing side effects from medications or vaccinations and it is going on longer than a day, consult your vet for help.


Stress is another reason cats can refuse to eat. Common stressors that can cause cats to lose their appetites are a major move, a new baby, new pets, a traumatic event or prolonged separation from owners.
