How Long Can Cats Go Without Food

Cats are obligate carnivores and require a diet that consists primarily of meat. If their food intake is not consistent with their natural predator-prey instincts, they can become ill and even die. While it’s difficult to calculate exactly how long a cat can go without food, experts generally recommend feeding them once per day and providing fresh water at all times.

How Long Can a Cat Go Without Food?

Cats are obligate carnivores, meaning that they require animal protein to survive. Because of this, cats typically eat once a day and can go up to three days without food if necessary. However, since cats are obligate carnivores, their bodies are not equipped to digest carbohydrates as well as animal protein, so they may develop problems if they go too long without food. Signs that a cat is starving include increased activity, loss of weight, and vomiting. If you see any of these signs in your cat, it is important to get them some food as soon as possible.

Can Cats Starve to Death?

What happens to cats when they go too long without food? Well, in the short term, they will likely become very weak and may even die. In the long term, however, if their diet consists only of water and no food at all, a cat’s body will start to break down its muscle and organ tissue until it dies. Some cats may last up to three weeks without food, but most will likely die within a few days.

Causes Of Feline Malnutrition

If you’re worried about your cat’s health and weight, you may be wondering how long they can go without food. The answer is, that it depends on the cat. Some cats will survive for weeks with no food, while others may only last a few days. Here are some factors that can affect how long a cat can go without food:

Weight: A thinner cat will usually go longer without food than a heavier cat. Cats who are underweight or obese may not be able to survive as long without food.

Activity Level: A sedentary cat will usually perish sooner than one who is constantly active. However, even an inactive cat can last a few days without food if his caloric needs are met by other means (such as freshwater).

Age: Young cats usually need more food than older cats and will typically perish sooner if their caloric requirements aren’t met.

Gender: Female cats typically need about 10 percent more calories than male cats to maintain their weight.

So, depending on a variety of factors – including weight, activity level, age, and gender – a cat’s chances of surviving for weeks without food range from 10 percent to 100 percent.

How to Determine if Your Cat Needs Feeding

One of the most common questions people have about their cats is when their next feeding is. This article will teach you how to determine if your cat needs feeding and how often to do so.

To determine if your cat needs feeding, weigh them and compare the weight to when they were last fed. Feed them if their weight is lower than it was when they last ate. If their weight has not changed, feed them once a day.

If your cat’s diet includes canned food or dry food, you can give them a small bowl of food once a day.

What to Feed a Cat When It Goes Without Food

When your cat goes without food, there are a few things you can do to help keep it healthy. You can feed them dry food, wet food, or a combination of the two. However, you may have to give your cat different types of food depending on how long they have gone without food. Here is a guide on how long cats can go without food and what to feed them:

If your cat has gone three days without food, it should be transitioned to a diet of dry food only. Do not give them water or moist food while they are on this diet. After three days, start slowly reintroducing water and moist foods to see how they react. If they respond negatively, then continue with the dry food diet.

If your cat has gone four days without food, it should be transitioned to a diet of both dry and wet foods. Start by giving them one wet dish per day for the first two days and then gradually reduce the number of wet dishes to one per day over the next two days. If your cat does not like the change from dry to wet foods, then try substituting one type of wet food for the other until they become more comfortable with the transition.

How Often to Feed a Cat When It Goes Without Food

How often should a cat be fed when it goes without food? While there is no set answer, feeding your cat regularly, even if it hasn’t had anything to eat in a while, is generally advisable. A study published in the Journal of Feline Medicine and Surgery found that cats who went more than four days without food exhibited signs of both malnutrition and stress. If your cat seems thin or isn’t acting like itself, give it a good meal to help it regain its energy.

What If My Cat Drinks Water and Poops Anyway?

Cats can go several days without food, but they will eventually need water. Cats cannot live more than two weeks without water. If your cat is not drinking enough water, you may need to give her some wet food or canned water to help her stay hydrated.

If your cat is drinking enough water and eating wet food or canned food, you may not need to give her a litter box. However, if she is not using the litter box, you may want to give her a sandbox in which to pee and poop.


There is no set answer to this question since cats are individuals and will respond differently to fasting than others. However, a general guideline would be to withhold food for around 12 hours before allowing your cat access again. Make sure you keep an eye on them throughout the fast so that any signs of distress (such as vomiting, diarrhea, or excessive panting) are noted and addressed as quickly as possible.
