Although cats are known for their love of food, there are times when they may go without eating for a period of time. Whether it’s due to illness, a change in routine, or simply a loss of appetite, it’s important to know how long cats can go without food and what signs to look for that indicate they may need medical attention.

What Happens When a Cat Goes Without Food?

Cats are relatively small animals, and as such, they can go without food for a shorter period of time than larger animals can. That being said, cats should not go without food for more than a day or two. If a cat does not eat for more than 48 hours, they may begin to experience liver damage. After three days of not eating, their liver may shut down entirely. If a cat goes without food for more than a week, they will almost certainly die.

When a cat stops eating, there are a few things that happen to their body. First, they will begin to burn through their stored fat reserves. Once these are gone, they will begin to break down muscle tissue in order to create energy. This can lead to organ damage and eventually death.

If you have a cat that has stopped eating, it is important to take them to the vet as soon as possible. They will likely need IV fluids and other treatment in order to survive.

The Dangers of Fasting

Cats are obligate carnivores, meaning that they require animal protein to survive. A diet lacking in animal protein can cause your cat to become malnourished. In addition, cats rely on a high level of protein in their diet to maintain their muscle mass. A lack of protein can cause your cat to lose muscle mass and strength.

Fasting for prolonged periods of time can also lead to liver damage in cats. The liver is responsible for filtering toxins out of the blood and breaking down fats. When the liver is not functioning properly, toxins can build up in the blood and cause serious health problems.

Prolonged fasting can also cause serious gastrointestinal problems in cats. The intestine relies on a continuous supply of nutrients from food to function properly. Without this constant supply of nutrients, the intestine can become weakened and unable to absorb nutrients properly. This can lead to malnutrition and serious health problems.

If you are considering fasting your cat for any reason, it is important to talk to your veterinarian first. They will be able to advise you on whether or not fasting is safe for your cat and help you create a plan that will minimize the risks associated with fasting.

The Risks of Starvation

Cats are obligate carnivores, which means that they require animal protein to survive. A lack of protein in a cat’s diet can lead to health problems and, in some cases, death.

While cats are able to survive for short periods of time without food, the risks of starvation increase the longer they go without eating. Some of the risks associated with starvation include:

– Dehydration: Without food, cats become dehydrated quickly. Dehydration can cause organ damage and failure, and is often fatal.
– Muscle loss: Without food, cats will begin to lose muscle mass. Muscle loss can lead to weakness and further health complications.
– Organ damage: Starvation can cause permanent damage to a cat’s organs, including the liver, kidneys, and heart.
– Death: Ultimately, starvation can lead to death.

How Long Can a Cat Survive Without Food?

Cats are fastidious creatures and usually have a very good appetite. However, there may be times when your cat doesn’t want to eat. Maybe they’re not feeling well, or perhaps they’re on a hunger strike because they’re protesting something (like a vet visit). Whatever the case, you might be wondering how long cats can go without food.

The answer to this question depends on a few factors, including the cat’s age, health, and weight. A kitten, for example, cannot survive without food for as long as an adult cat. A sick cat also won’t be able to go without food for as long as a healthy one. And, finally, a heavier cat will be able to survive without food for longer than a lighter cat.

With all of that said, a healthy adult cat can usually survive without food for about two weeks. Kittens, on the other hand, will only survive for about three to four days without food. So, if your cat hasn’t eaten in a few days, it’s important to take them to the vet to rule out any underlying health problems.

How to Safely Fast Your Cat

While a lot of people think that it is cruel to fast a cat, the truth is that there are many benefits to doing so. Cats are obligate carnivores, which means that they require animal protein to survive. A fast gives their digestive system a much-needed break from processing all that animal protein.

There are also benefits to fasting your cat for health reasons. For example, if your cat is overweight, fasting can help them lose weight in a healthy way. Fasting can also help improve kidney function and reduce inflammation throughout the body.

If you do decide to fast your cat, it is important to do so safely. Make sure to consult with your veterinarian first and always provide plenty of fresh water. Start with shorter fasts and slowly increase the duration as your cat gets used to it. Avoid fasting for more than 24 hours at a time.

What to Feed Your Cat During a Fast

If you are planning on fasting your cat for any length of time, it is important to know what to feed them during their fast. While cats are able to survive without food for a period of time, it is not advisable to fast them for more than a day or two. If you must fast your cat for longer than that, it is important to consult with your veterinarian first.

There are a few things that you can feed your cat during a fast that will help them stay healthy and avoid any problems associated with fasting. These include:

-Wet food: Wet food is easier for cats to digest and contains more moisture than dry food. This will help keep your cat hydrated during their fast.
-Broth: You can make your own broth by boiling chicken or beef in water. This broth can be fed to your cat during their fast and will help them stay hydrated and get some nutrients.
-Canned tuna: Canned tuna is high in protein and moisture and makes a good option for feeding your cat during a fast. Be sure to choose tuna that is packed in water, not oil.

How to Break Your Cat’s Fast

If your cat is healthy and has a good appetite, there is no need to worry if he or she misses a meal or two. However, if your cat stops eating altogether, it is important to take action. A prolonged fast can lead to serious health problems, including liver damage and malnutrition.

There are a few things you can do to break your cat’s fast:

-Offer small amounts of wet food or high-quality canned food.
-Add some warm water to the food to make it more appealing.
-Try offering a small amount of tuna fish or chicken (without bones).
-If your cat still refuses to eat, contact your veterinarian for further advice.

When to Seek Veterinary Care

If your cat refuses to eat for more than 24 hours, it is time to seek veterinary care. Prolonged refusal to eat can lead to serious health problems, including liver disease and pancreatitis. If your cat is showing any other signs of illness, such as vomiting, diarrhea, lethargy, or weight loss, you should also seek veterinary care.


In general, a healthy cat can generally go without food for about a day. However, if your cat has a medical condition that requires special dietary considerations, please consult your veterinarian for specific guidance.
