How Long Can a Cat Go Without Food or Water? A cat can go without food for about one to two weeks if they have access to water, but they can only survive without water for about three to four days.
However, prolonged periods without proper nutrition or hydration can lead to serious health problems.
Cats are prone to liver issues and dehydration when deprived of food or water, so it’s critical to address these needs promptly if they stop eating or drinking.
How Long Can Cats Go Without Food?
Cats can survive up to two weeks without food, but this is not safe as they rely on nutrients from food for essential functions.
Going without food for just a few days can lead to serious health risks like hepatic lipidosis (fatty liver disease), which is life-threatening and develops when the body breaks down fat for energy, overwhelming the liver.
Malnutrition also sets in, leading to muscle wasting and weakened immunity.
If your cat refuses to eat for over 24 hours, watch for signs like lethargy, weight loss, or unusual behavior, and consult a vet promptly.

How Long Can Cats Go Without Water?
Water is crucial for a cat’s survival, and while they can last up to two weeks without food, they can only survive about three to four days without water.
Dehydration can quickly lead to severe health issues such as kidney damage, electrolyte imbalances, or even organ failure, as cats rely on hydration for essential functions like temperature regulation and waste processing.
Symptoms of dehydration include dry gums, lethargy, sunken eyes, and loss of skin elasticity. If you notice these signs, it’s vital to encourage water intake and seek veterinary care promptly.

What to Do If Your Cat Isn’t Eating or Drinking
If your cat isn’t eating or drinking, it’s vital to act quickly. Cats can go downhill rapidly if they don’t receive proper nutrition or hydration.
- Warming up the food: Slightly warming up wet food can release more aroma, which may help entice your cat to eat.
- Different flavors or textures: If your cat is being picky, trying different flavors or textures might help get them to eat.
- Provide fresh water: Cats are more likely to drink fresh, clean water. Change the water in their bowl at least once a day.
- Use a water fountain: Many cats prefer running water, so a cat water fountain can encourage them to drink more.
- Add water to their food: Mixing a little water into wet food or kibble can increase your cat’s fluid intake.
If your cat continues to refuse food or water for more than 24-48 hours, contact your vet immediately for further evaluation and treatment options.
