A young and healthy cat’s body consists of 70% water, given that state, it can survive for 4 to 5 days without water. As your cat gets older, the lesser the liquid is in the body. This means dehydration is faster for older cats as their internal water reserves are scarce.

1. Weight

Large breed cats like Birman and Persian cats need more water than smaller breeds like Siamese and Munchkin. In case you care for cats with differing sizes, don’t be surprised if you see your bigger fellow ‘gulping’ more water than the little ones.

2. Food Type

What kind of food do you serve for your kitty? Is it the dry or the wet type? If you give the dry type, then you should provide your pet with more water. Why? Because your cat will be chewing crunch and will take a bit longer to finish its dry food.

Not only that, the dry or kibble food only contains an average of 7-12% moisture as compared to the moisture content of wet food which is around 70-80%. Such a huge difference.

3. Age

Elderly cats can get dehydrated faster than young ones. Thus, older cats need to drink more.

4. Weather

Is your cat an indoor or outdoor cat? An indoor cat will survive longer without water compared to those living outside, especially during the summer season. Though outdoor cats hunt and receive water from their prey, still, if the temp is scorching hot, cats cannot go without water for long days.

How Do You Know If your Cat Is Drinking Sufficient Water?

Let’s do small math- For instance, a cat weighs 10 pounds and eats dry food, then it should consume one cup of water a day.

On the other hand, if your cat eats wet food, it requires less water – 2/3 cup of water is sufficient for a 10-pound pussycat.

There is another way of computing:

Give 20 to 40 ml of water for every kilogram of body weight. Multiply the weight of your cat to 0.03. Then multiplied by 1000. So for example, if your cat weighs 7 kilos, it should drink about 210 ml of water each day.

When your cat stops eating, its body will rely on its fat reserve for energy.

However, in case your cat does not want to eat and drink, then it will not survive for a week. There is a major difference between your cat not eating and your cat not drinking in terms of damage done in the vital organs.

Let’s say that your cat does not show any interest in its food. The consequence would be lethargy because there are not enough nutrients in its body. But the moment it touches its food again, its energy will normalize again and you’d see your feline pet back on its feet.

In contrast, in case your cat stops drinking water, it will have a damaging effect on its organs. Dehydration results in kidney, liver, and other organ failures. If dehydration extends, then severe organ damage is inevitable that can result in death.

And, if your sick pet continues to shoo away its food, the chance of hepatic lipidosis is high.

This is a liver condition wherein the body uses fat reserve to survive. But you have to understand that your cat’s system is not designed for this. The liver will work harder to process fat. A few of the signs of hepatic lipidosis are jaundice, diarrhea, vomiting, and drooling.

How to Encourage Eating and Drinking?

We have some advice that can encourage your pet to drink more:

  • Place water bowls of different shapes and sizes around your home. Why? Because some cats are more attracted to large water bowls as these resemble clean lakes.
  • Distinguish your cat’s preference for water-does it prefers cold or hot or room temp water?
  • If a cat were to choose, it would select glass or ceramic over metal or plastic water bowl. In short, your cat may be a bit ‘quirky’ when it comes to the material of the water bowl.
  • Some cats prefer to drink running water and not still. This is why we recommend that you look for a cat fountain drinker.
  • Maybe a cat is asking for milk instead of water.
  • Healthy treats like fresh watermelon and frozen fruits or broth are awesome ways to stay hydrated.

How to encourage your pet to eat?

  • If you are feeding dry food, try adding some water from a tuna can or anchovies for flavor.
  • Try warming the food in a microwave for a few seconds. Nobody wants a cold meal.
  • Let your cat eat alone, away from your other pets.
  • Try hand feeding your pet especially if it is sick.
  • If a cat is in a dry food diet, you may want to shift to a wet food diet. Or you can mix the dry and the wet food.

This is what you can do for a cat not eating or drinking:

  • If it is mildly dehydrated, give it a small amount of electrolyte solution like Pedialyte every 10 minutes for an hour.
  • Do your best to dropper feed your cat.
  • In case a cat is vomiting, licking ice chips will do the trick.

But for severe dehydration, rush your pet to the Vet to save its life.
