How Long Can CATS Go Without EATING? (I’m Worried!)

How long can a cat live without eating? As a pet owner, you're probably worried sick every time your pet refuses to eat. Your concern is understandable - we’d be worried too.

Loss of appetite in humans is an indicator that something is not right in their body, and the same may be true for cats. This condition can have many different causes, and we're going to go over as many of them as possible in this article.

Just keep an open eye and observe any signs that your cat is manifesting so you can determine if he or she needs to be taken to a vet. In most cases, it could be just a phase that will soon blow over.​

Stay Calm, Cats Sometimes Do That

As a pet with a complex personality, a cat can stop eating for any number of reasons, and not all of them are a cause for concern. Understanding the underlying reason is not a trivial task. However, while doing so, it is important to stay calm, and not do anything drastic.

So, How Long Can a Cat Live Without Eating?​

​For a pet - or any animal for that matter - to live and function properly, it needs proper nutrition. This means that a cat has to eat regularly. She also needs to drink water.

It is important to note that a cat gets most of her water from the food she eats. You might want to keep tabs of your cat's intake, and if you notice that she doesn’t eat the food you give her, then it is time to check if your pet is eating elsewhere.​

If she isn’t, check if she is drinking water.

A cat can live up to two weeks without eating as long as she is still drinking water. But if the cat is also not drinking water, she won’t live for more than a few days.

If your cat is not eating nor drinking at all, bring her immediately to the vet for a check up.

One major difference between a cat not eating and a cat not drinking water is the damage it can do to your pet's internal organs. Any animal not eating for days will gradually lose energy and nutrients required to function. Once they have eaten, they can very easily get back to their old self.

​In contrast, an animal that does not drink water will not only fail to function but will also experience internal organ damage. Water is important for the function of all the organs in the body.

Dehydration damages the kidneys, and liver and other organs. Extended periods without drinking water will cause these organs to have long term damage and eventually, death.

​In case, there is no food or water, the first to shut down is the stomach, and then the kidneys, and the liver. The last to go would be the heart and then the brain. Irreparable damage can be done to these organs if your pet does not eat or drink.

What to Do if Your Cat Stops Eating?

​Bringing your cat to the vet is the first thing you need to do. The vet would treat this as an emergency and will start treatment by attaching a fluid drip to quickly rehydrate your cat’s body.

​After an initial examination, and being sure that the cat does not have any injuries, the vet will recommend admitting your pet so she can be properly treated.

In case a vet is not available, you have to find ways to feed your cat and ensure she is drinking water. Using a dropper, you can feed her water in regular intervals. You can also give her much-needed nutrients by feeding her soft foods.

What are your pet’s favorite foods? Tuna? Biscuits? This might not be enough for a solid meal, however, but it can help nurse your pet until she becomes healthy again. We recommend a high nutrition supplement like Nutri-Cal, which you can buy on Amazon.

You can even try giving her tuna water – it seems to work in rehydrating a cat without food.

​Possible Reasons Why Your Cat Refuses to Eat

A cat is a complex animal and it is not entirely uncommon for pet owners to lament and say “my cat is not eating”. There are a lot of possible causes for her refusal to eat.

One reason, as mentioned earlier, is a health problem. She may be hurt or sick. This can be anything from an injury to a simple case of indigestion. It can also be a symptom of diabetes. Some cats even experience what’s called feline depression. Whatever it is, only a vet can tell for sure.

If your cat does not have any appetite at all, you should have at least some idea why she’s acting like that. There are some things you can try such as giving her a cat food or switching to another brand of cat food. Or perhaps she might also need a change of scenery, or anything that might help to make her feel motivated.

​There are a lot of different cat food products available in the market. You can introduce your pet to as many of these products as possible and see which ones she likes.

​It may require some trial and error, and let me just warn you, it might take some time. Moreover, your cat's personality should also be taken into consideration, and she should be given some time to get acquainted with the new flavors.

​It is also worth noting that after a long time of being on the same diet, it may be that it has dulled the cat's taste which is exactly why you should consider giving her another kind of food or perhaps just buying another brand.

Other Health Threats to Worry About If Your Cat Doesn’t Eat

One long term damage is fatty liver disease or hepatic lipidosis (HL). When a cat’s body does not have enough water or if she does not eat for an extended period of time, she may become susceptible to acquiring HL.

A larger or fatter cat would be more prone to it, as the body loses weight, the first to go would be fat and liver fat would not be affected. This may cause an imbalance in the body and eventually lead to the onset of the disease. Only a vet can determine this for sure, by means of a liver biopsy.

There are several reasons why cats don't eat. It could be because of depression, or your cat may just be looking for variety in her diet. If after trying something new, your pet is still not interested in food, it may be time to bring her to the vet for a checkup and tests.

Your pet may have diabetes, liver problem, or a heart condition. Either way, only lab tests and scans can confirm your suspicion.

​The important thing is to be observant and try to be as responsive as you can to your pet’s needs. The sooner you spot the signs and symptoms the better, so your cat can receive treatment as soon as possible and thus prevent any further damage to her body.
