How Long Can A Cat Go Without Eating? What You Need To Know


How long can a cat go without eating? I’m sure everyone has wondered at one point or another about this question. It can definitely get nerve-wracking when your cat no longer is reminding you that they are hungry.

If your cat starts to show signs that it no longer have an appetite, you may start to ask yourself, how long can my cat go without eating? The short answer is not very long. If your cat hasn’t eaten or drunk in 36 hours, it’s time to see a vet. However, there are a number of different factors that will impact this answer, and we will dig into those below.

How long can my cat really go without food or water?

​For a cat (or dog), to live its best life, it will need proper nutrition in the form of food and water. Typical cats normally get most of their water from the food they eat.

The real danger when it comes to cats not eating is the inability to get water. A cat is in much more danger if she does not get water as compared to food. Studies have shown that cats can live up to two weeks without food. As long as they are still drinking water, they should be fine for this length of time.

This is mainly because not having water can do permanent damage to your cat’s internal organs. Water plays a key role in keeping your cat’s internal healthy. By day 3 of no water, your cat’s body will completely fail.

With food, however, your cat should be able to get back to his/her regular self after they start eating again regularly. Even if they do not eat but still get their water intake, they may be able to go as long as two weeks.

If you notice that your cat is not eating or drinking for more than 36 hours, it’s time to bring them to a vet. Your vet may administer an IV to your cat to help prevent any permanent internal damage.

“Everything I know I learned from my cat: When you’re hungry, eat. When you’re tired, nap in a sunbeam. When you go to the vet’s, pee on your owner.”
