How Long Can Cats Go Without Water? How Much Should Cats Drink?

How long can a cat go without water?


As with basically all animals, cats require food and water every day. They won’t die if they miss eating and drinking for a day or two, but for the sake of their health, they shouldn’t be underfed or underwatered on purpose – preparation for surgery being one obvious exception.


Most people are asking how long can cat’s go without water because they are going to spend an extra day on holiday somewhere, they are unable to get home for other reasons, or they fear their cat is trapped in a shed. Here’s hong long cats can go without access to water.

How long can a cat live without water?


I remember years ago our poor cat Muffin was accidentally locked in a neighbor’s garden shed. We estimate that she was in there for at least 3 or 4 days. She came out visibly thinner and bedraggled, but she survived. So if you’re asking ‘how long can a cat survive locked in a shed?,’ know that under the best conditions for survival, you should have a few days.


However, it’s going to depend on the conditions. For example, my cat was trapped in a cool dark shed for days without water, but if it had been a hot sunny glasshouse, no doubt she would have perished. Needless to say, we didn’t get many cat kisses for a while after that!


Factors that will determine how long your cat will survive without water:

  1. Temperature
  2. Whether or not there is a shelter
  3. How healthy the cat is
  4. When and how much water the cat last drank
  5. The age of the cat
  6. The cat’s breed and heritage
  7. Overall stress tolerance of the individual cat


So you see, each cat will have a different suitability time with water. However, we can say that it is anything from a couple of days in the worst conditions, up to 2 whole weeks in the best conditions. As with humans, water is more important than food for cats.


If a cat is deprived of water for too long though, even though it may survive there could be irreparable damage done to the cat’s organs and bodily processes.



In the video above, you will learn that the owner of a cat rescue center passed away with many cats in her care.


These cats were without water and food for up to 2 weeks. Some of the cats died or had to be put down due to their bad condition, whereas others survived the ordeal and were rehomed.


And if you were wondering how long a kitten can go without water, then it’s generally even shorter than an adult cat. A kitten is more susceptible to becoming dehydrated and dying through thirst.

Healthy cats will last longer and come out better off than a cat that is already malnourished or ill. Giving the best food for kittens or cats will ensure that they are strong and healthy if, god forbid, they do ever become trapped in a situation where they have to go without water or food for some time.


Dehydrated Cats



If you suspect your cat is dehydrated it’s best to take her straight to the vet. In some locations, you could even book a home vet visit with The Vets, which means no pet carriers, waiting rooms, and undue stress on your cat.


They can get her sorted out with electrolytes and/or other methods to get her feeling better. It may be that she has a medical condition, such as diabetes or kidney failure, that is causing dehydration or a lack of desire to drink water.


Cats generally prefer to get fluids from their foods, and some cat foods will have higher water content for just that reason. Good wet cat food will help your puss to hydrate and mean she will drink less from a water bowl.

How Long Can A Cat Survive Without Water?


So, how long can a cat survive without water?


Not long!


For best outcomes, you don’t want your cat going more than a day or two without drinking water. However, your cat will likely come out unscathed if they go 3 or 4 days without water (assuming they are in a cool dark space). However, anything beyond 4 days and your cat will start to suffer the consequences of dehydration.


It’s even more important that pregnant female cats and/or kittens also have unlimited access to water and not be left without it at all. Pregnant cats or kittens can have long-term damage done to them by becoming dehydrated.
