How Long Can A Cat Go Without Water? Learn All About Dehydration In Cats

Cats can be both affectionate and aloof or playful and lethargic, as they are animals with a lot of moods. Yet, caring for a cat is easy, once you’ve gotten used to having it around the house and established a routine with it. Feeding and giving water to a cat is easy since all you have to do is keep food and water available and your cat will eat or drink when it feels like it.

But have you ever wondered how long a cat can go without water? While you wouldn’t want to test this out on your own cat, it can be quite a head-scratcher. For whatever reason, if you are curious about how long a cat can go without water, read on for more information about how to care for your pet better.

How much water do cats need?

Usually, you just leave a bowl of water out for your cat, and it will drink whenever it’s thirsty. But do you know how much water your cat actually needs? A cat’s water intake depends on a number of factors. However, you can know if it’s getting enough water by observing your cat and looking for some signs. Below is a list of useful information regarding needed water intake for cats:

  • The water requirement of a cat depends mainly on its size – smaller or younger cats require less water than bigger or older cats.
  • The food you feed to your cat is also a factor. If your cat eats only dry cat food, it needs more water. However, if you feed your cat wet or canned cat food, which is about 80% water, it needs less to drink.
  • On average, a cat needs to drink 2-4 ounces of water on top of the food it eats.
  • You know your cat is getting enough water if its skin is elastic and its coat is shiny and free of dryness and flakes.
  • Your cat is active and does not sleep all the time.
  • Your cat urinates regularly.

Now that you know how much water your cat needs, let’s move on and find out what happens when your cat doesn’t drink enough water. After that, we will discuss how long can cats go without drinking water.

How long can cats go without water?

When we have a pet, we try our best to give it love, affection and fulfill its basic needs, such as food and water. But what happens when you accidentally lock your kitty inside the house along with the house key? Or worse, you go out of town and forget to leave adequate food and water for your cat? How long can a cat go without drinking water? Would it perish within a day or can you leave it for a week, confident that you’d come home to a happy, albeit very thirsty, cat?

In fact, an average house cat can only survive for a few days without water. As long as your pet has a water source available in your house, your cat will be able to survive, even if you forget to leave food for it. However, without water, you cat will most likely die within a week because water is much more essential to their health than food. Without water, a cat will experience hepatic failure and its muscle mass will catabolize, causing a slow and painful death for your poor pet. Rarely do house cats survive being left without water so it would be wise to leave your cat with an ample supply of accessible food and water when leaving your cat home alone.
