How to Get a Cat to Drink More Water: Fountains, Food and Tips
Water is the most important nutrient, yet many cats drink less than they should. Their ancestors lived in deserts, and their bodies still conserve water by producing concentrated urine. Modern cats that eat dry food and drink little face a higher risk of urinary crystals, stones and kidney problems. A few simple changes make a difference.
How much water does a cat need?
A rough guide is about 50 to 60 milliliters per kilogram per day, which is roughly 3.5 to 4 ounces for a ten-pound cat, counting the water in food. Cats on wet food take in most of this through meals, while cats on dry food must drink far more. See wet vs dry cat food.
Signs of dehydration
- Dry, tacky gums
- Sunken eyes
- Lethargy and weakness
- Skin that stays tented when gently lifted over the shoulders
- Poor appetite
- Constipation
- Dark or strong-smelling urine
Dehydration can be serious, particularly in kittens and seniors. See the emergency warning signs guide, and use the US vet directory to find a clinic.
Why hydration matters
Water supports kidney function, digestion, circulation and temperature control. Low water intake concentrates urine, raising the risk of crystals, stones and blockages. See signs of a urinary blockage in cats. It also matters for cats with kidney disease. See chronic kidney disease in cats.
Ways to boost water intake
Feed more wet food. The simplest method. Wet food is mostly water, and some owners add a spoonful of warm water to meals.
Use several bowls. Place water in multiple locations, away from food and litter, since cats prefer water that is separate from their food.
Choose wide, shallow bowls. Some cats dislike whiskers touching the sides. Glass, ceramic and stainless steel are easy to clean and do not hold odors like some plastics.
Try a fountain. Many cats prefer moving water. Choose a model that is easy to clean, and wash and refill it regularly, replacing filters as directed.
Keep water fresh. Change bowls daily, and wash them to remove biofilm.
Offer variety. Some cats like to drink from a dripping tap, a glass or a cup.
Add flavor, carefully. A teaspoon of water from tuna packed in water, or a low-sodium broth made without onion or garlic, can tempt some cats. See are onions and garlic toxic to cats. Do not add milk. See can cats drink milk.
Make ice treats. In summer, ice cubes with a hint of tuna water entertain some cats. See keeping cats cool in hot weather.
Play and routine. Active cats drink more. Encourage exercise with play and enrichment.
Where to place bowls
Cats like quiet places where they can see their surroundings. Avoid putting water next to the litter box or a noisy appliance. In multi-cat homes, place stations in several rooms so that one cat cannot guard them. See how to introduce a new cat to your cat.
When thirst is too high
A sudden increase in drinking, with more urination, is a sign of illness. It can indicate diabetes, kidney disease, hyperthyroidism or other conditions. See diabetes in cats and hyperthyroidism in cats. Measure how much your cat drinks over a day or two and report it to your vet.
Special cases
Senior cats. Offer extra water stations and wet food. See the senior cat care guide.
Cats with urinary problems. Vets often recommend wet food and more water. Follow your vet's instructions.
Kittens. Provide shallow water once weaned. See kitten feeding schedule.
Hot weather. Cats need extra water and cool spots.
Water quality
Use clean tap water, or filtered water if your cat likes it. Avoid contaminated sources such as puddles or fountains in parks. If the local water is poor, ask your vet.
Measuring intake
To see how much your cat drinks, fill the bowl with a measured amount of water, note how much remains after a day and allow for evaporation. In multi-cat homes this is harder, so watch for changes in the litter box, such as larger clumps, instead. Report anything unusual to your vet.
Making it a habit
Offer fresh water whenever you serve meals, and clean bowls every day. If you move the bowls, move them gradually. Cats are creatures of habit, and a stable, quiet water station is more likely to be used than a bowl in a busy hallway. Consider several types of containers to learn what your cat prefers, and keep what works.
Fluids from the vet
Cats with kidney disease or other conditions may need subcutaneous fluids. Your vet can teach you how, if needed.
Frequently asked questions
