How long can cats go without water? Are cats able to survive a long time without it, or do they get dehydrated pretty soon? Cats are often found to drink too little water, even when they have it available, and in the long run, it can create health problems for them.

Cats survive between 1 to 3 days without water, then severe dehydration sets it causing them to get sick, and if not resolved, it can be fatal. So even though some cats have managed to survive up to two weeks without water and food, it is not always the case for all cats.

Let’s go into more detail.

How long can cats go without water?

WHAT HAPPEN IF A CAT DOESN’T DRINK?

Cats are not famous because of their habit of drinking water. In fact, they are most known to avoid water and not to drink too much. However, it is essential to remember that part of cats’ daily water intake comes from food. Therefore, for cats on a wet food diet, the risk of dehydration is much less than cats on dry food.

Numerous problems derive from lack of water. Some of the most evident symptoms are:

  • Weakness
  • Little appetite
  • Drooling
  • High heart rate
  • Sticky gums
  • Trembling
  • Excessive urination or infrequent urination
  • Panting
  • Weak pulse
  • Constipation
  • Sunken eyes

But, how much water does a cat need? Here is a helpful table already provided in another article.

At the first symptoms of dehydration, a cat should visit the vet to find any underlying reason for it and get immediate attention, like fluid and other medications.

HOW LONG CAN CATS GO WITHOUT WATER?

Cats do not take their water only from drinking but also from food. Since they are small animals, they do not have a lot of reserves within their body that allows them to survive for a long time.

Cats can’t go for more than three days without drinking, even though some cats became known for surviving up to two weeks without water and food. Obviously, they were in horrible conditions.

But besides the extreme cases of cats who manage to survive for a more extended period smartly, typically, cats do not have that much strength. House cats are used to be fed and given water. If they escape or find themselves lost, they could survive for a while outside, living with what people give them or what they can find.

Sometimes cat owners have to leave their cats alone for a few days. If so, make sure you leave plenty of water supply around the house and food. But water is more important. They can survive longer without food than without water.

WHAT CAN I DO TO GET MY CAT TO DRINK MORE?

If your cat is not a drinker and if you are worried that he can go for days without drinking, or even a day or several hours, here are some tips for you to follow.

1. USE MORE WATER BOWLS

Cats used to roam around the house. If they find more places with water, they are more likely to drink. Give them ample choices. Maybe they do not like to drink from the water bowl near the food or like a specific bowl better. Try also to use different bowls to see if your cat prefers one instead of another one.

2.WATER FOUNTAINS

Cats are fascinated by running water. If you let the water run from the bathroom sink or the kitchen sink, you will find your cat looking at it intrigued. Some cats will try to drink, and some others will try to play with it.

If you use water fountains, you see that your cat will be attracted to them and drink more than usual. You can find a good selection of cat water fountains to choose from in many pet shops. The trick is to choose one that your cat may like and may find attractive.

3.CLEAN THE WATER BOWL OFTEN

Cats are obsessed with cleaning and clean things. If the water is dirty or the water bowl is dirty, cats may stay away from it and not drink. Washing water often bowls, cleaning the drinking fountains, and changing water often are all things that keep cats happy and drinking.

4.USE A LOT OF WATER

Fill the water bowls to the top and if you use a drinking fountain, place a lot of water in it. Cats may not like to dig to the bottom of the bowl to drink due to their whiskers. A lot of water can also attract them toward the bowl or the drinking fountain.

5.COMPLEMENT CATS WATER INTAKE

Cats take part in their daily water intake from food. Wet food has a higher moisture level. Therefore if you have a cat not drinking much, try to switch him to a wet food diet. It can help your cat to get the water he needs to stay healthy.

6.IMPROVE WATER QUALITY

Tap water is not always the best choice. My cats drink the same water I drink. I buy bottles for them too. Tap water is chlorinated and tastes terrible. They may not like it. You could filter tap water or give them water from bottles. This alone can prompt your cat to drink more.

7.FLAVORING WATER

Adding bone broth or tuna water to your cat’s water bowl can encourage your cat to drink more. Maybe try to do this with an additional water bowl to see how your cat reacts.

Those are only a few of the things you can do. Observe your cat and see what he does and what he likes. Maybe you can come up with more tricks to get your cat to drink more.
