Reasons your cat isn’t eating or drinking

Cats are like children and have to be trained to eat and drink. Don’t just assume your cat will be a good eater. Cats often prefer a specific food brand, just like people do. Your cat may not eat or drink because she is feeling too stressed, in pain, or if she has a health condition like a bladder/kidney infection.

Cats will become dehydrated without water and can starve without food. So the most important thing is to get her to eat and drink. Here are some common reasons why cats don’t eat or drink. Your cat may not be eating or drinking for a variety of reasons. If your cat is experiencing the following symptoms, it’s essential to take them to the vet as soon as possible:

  • Vomiting
  • Diarrhoea
  • Lethargy
  • Loss of appetite
  • Weight loss
  • Excessive urination
  • Dehydration
  • Constipation 

Colds in cats are common, and your cat may just be sleeping more during the day due to being under the weather. Cats can also stop eating or drinking if they’re stressed by a change in the household, like the arrival of a new baby, a new pet, new furniture, etc. You should always ensure you’re up-to-date on your cat’s shots, including the yearly feline immunizations. Always wash your hands before touching your cat, and keep your cat’s litter box nice and clean.

How Long Can A Cat Go Without Water

Cats are known to be picky drinkers. Even when they are thirsty, they don’t drink right away. They usually lick water droplets off their fur or drag their tongue across wet surfaces to get the moisture they need. Cats are resilient, so it is unlikely that a cat will die from 3 days of missed water. If a cat is not drinking, he is probably not eating. If a cat fails to eat for 3 days, he is likely to enter a catatonic state and die after several more days.

If your cat refuses water, then you need to figure out why. Cats almost always drink water when eating, so you should be worried if you find a cat that is not drinking and won’t eat. It takes very little water a day to keep a cat alive, so a cat that stops drinking will die in a few days. A cat not drinking water will typically be listless, so if your cat is lifeless and not drinking, this is a cause for concern.

How Much Water Do Cats Need?

It depends on the type of cat, but the general rule for cats is to give them at least 2.5 ounces of water per pound that they weigh. So, a 15-pound cat should get at least 37.5 ounces of water. A cat needs about 1 liter of water for every 10 pounds of its body weight. Cats can get all the water they need from their food, so giving them a separate bowl to drink from is unnecessary. A cat that doesn’t drink enough water might develop urinary tract infections and kidney problems. Dehydration is a complication of diabetes that can also lead to high blood sugar levels.

What Are the Risks If My Cat Isn’t Drinking Water?

How Long Can A Cat Go Without Water?

If your cat is ordinarily active and drinks plenty of water, then you shouldn’t worry if your cat isn’t drinking water. However, if your cat is usually sedated and isn’t drinking water, it can be a sign of a medical condition.  The following are some of the issues related to cats not drinking water.  It is a medical emergency if your cat is experiencing any of these issues:

As said earlier, cats usually drink water available at home. If they don’t drink water, then you should be worried. It could be an indicator that something is wrong. Some causes that might lead to dehydration are  1—illness  2. Feline bladder stones  3. Blockage of the urinary tract  4. Urinary tract infection (UTI)  5. Hypothyroidism  6. Kidney disease  7. Excessive Stress  8. Environmental distress  9. Improper feeding  10. Exposure to a toxic substance like salt, heavy metals, antifreeze, ethylene glycol, etc. The risk associated with dehydration is that it can cause kidney failure. The consequences can be fatal, so if your cat is not drinking water, it is high time you take him to the vet.

How to care for a dehydrated cat?

Dehydration can cause lethargy, bad skin and fur coat, weight loss, and even death if severe. So it is vital to take care of your cat’s hydration. Cats are more prone to dehydration than other pets. They don’t have the excellent thirst reflex that other animals have. As long as they have water, they’re fine. So it’s up to you to ensure they’re getting their H2O.

Mixing vitamins or medication into the water bowl can be difficult to tell if they’ve consumed enough to be effective. Always make sure the water bowl is clean and full of fresh water. Just like humans, cats need plenty of water to stay hydrated. If your cat is dehydrated and not getting enough water, then your veterinarian may recommend giving it water with electrolytes.

Why do cats hate water?

Cats hate water because they’re afraid of drowning. They naturally fear being in the water and are not very good swimmers. Cats are also known to be squeamish about water, which is why they don’t like baths and other forms of grooming. Cats are probably the most aquatic animals but they can’t swim like dogs or humans.

Their webbed feet and hands make them great at climbing, and their fur dries out quickly when wet. Their head and neck are strong, so even if a cat goes underwater for only a few seconds, it can surface safely. But cats can’t hold their breath for long periods or go without food or water for a long time—they need to consume both regularly to stay healthy. So if your cat is in the water, it’s because he’s trying to get out!

How you can help

If you know the signs, a cat can live up to three weeks without water. According to the ASPCA, if a cat is mildly dehydrated, the best thing to do is supply it with plenty of water. You should contact your veterinarian if you notice your cat is only drinking very little. You can offer water in a shallow dish to ensure it is consuming. If your cat’s water intake doesn’t increase, take it to a vet.


What happens to cats if they don’t drink water?

The sharp answer is-nothing. Cats are susceptible to water and will not drink if it is saline, polluted, or infested with bacteria. Cats can go a long time without water and live for up to a week without food but only three days without water. So if your cat does not drink water for more than three days, take it to a veterinarian immediately.

What is the longest a cat has gone without water?

It is not healthy, but some cats have been known to survive 20 days without water. Cats can last longer without food, although this is not recommended. If a cat is in a situation with no water, we should give it some water rather than wait for too long since this may cause organ failure.

Can cats go for 48 hours without water?

Cats can survive longer without water than dogs, but they should never be deprived of water for more than 24 hours.  Water is essential to their survival, just like it is to humans. A cat’s thirst mechanism is not as sensitive as a human’s. Their body can go longer without water than a dog can. A dog can last about 48 hours without water if it is not active.


Cat owners should keep a water bowl out for their pets, especially if they are gone for an extended period. If the cat doesn’t drink, try different things. Some cats prefer a drier bowl to get the water they need. Also, if it’s too cold, the cat will not want to drink the water because it’s uncomfortable. If the cat seems too tired to drink, try warming up the water. If all else fails, the vet is a good place to go.
