You know the feeling: you fill the bowl, you change the water, you even try a fancy new fountain. And your cat just… stares at it. Then walks away. It’s frustrating, and honestly, a little scary. Cats are notorious for not drinking enough, and when they’re already dehydrated or feeling off, getting them to take a sip can feel impossible. But you can absolutely help. Here’s exactly how to rehydrate a cat that won’t drink, using real strategies that work without a fight.
Start with the Bowl Itself (Yes, It Matters That Much)
Before you try any tricks, look at the bowl. Cats have very sensitive whiskers. If the bowl is deep and narrow, every sip means a painful whisker cramp. Switch to a wide, shallow dish, ideally ceramic, glass, or stainless steel. Plastic bowls can hold smells and cause chin acne, which makes your cat avoid the bowl entirely. Many cats also prefer moving water. A simple pet fountain can be a game changer. And if your cat has arthritis or neck pain, an elevated bowl makes drinking much more comfortable. If you think that might be the issue, check out our guide on Need Elevated Cat Bowls? Our 5 Top Picks for options that can help.
Water Flavoring: The Sneaky Hydration Hack
Plain water is boring. Your cat is a predator, and in the wild, they get most of their moisture from prey. You can mimic that by adding a little flavor. Try adding a splash of unsalted chicken broth (no onions or garlic, ever) or the juice from a can of tuna packed in water (not oil). A few drops of low-sodium clam juice can also work. Stir it into their water bowl, and the smell alone might trigger a drink. You can also freeze that flavored liquid into ice cubes and drop one in the bowl for a fun, slow-release hydration treat. Just keep the portions small so you don’t upset their stomach.
Switch to Wet Food (The Single Most Effective Move)
This is the number one trick in the book. Dry food has about 10% moisture. Wet food has 70 to 80% moisture. If your cat won’t drink, you can solve most of the problem by feeding them canned food. Add a tablespoon of warm water to the wet food and mix it into a soupy pate. The warmth releases the aroma, making it even more enticing.

You can also offer unflavored Pedialyte (a few tablespoons) mixed into the food, but ask your vet first, especially for kittens or cats with kidney issues.
Use Broth-Based Treats and Syringes (Gently)
Sometimes you need to get water in, and they won’t eat or drink at all. In that case, you can use a syringe (no needle, of course) to gently squirt water or broth into the side of their mouth. Never squirt down the throat, it can go into the lungs. Aim for the cheek pouch, and go slowly. Give them a few milliliters at a time. You can also buy broth-based cat treats or bone broth pouches specifically made for cats. These are often a hit even with sick cats.

A cat’s kidneys are incredibly efficient at conserving water, which is why they can go a long time without drinking in the wild. But in a modern home with dry kibble, that same efficiency can backfire and lead to chronic dehydration. A little extra moisture in their diet goes a long way.
When to Worry: Signs of Dehydration
You need to know the difference between a picky drinker and a medical emergency. Gently lift the skin between your cat’s shoulder blades. If it snaps back immediately, they are hydrated. If it stays tented or goes back slowly, they are dehydrated. Other signs: dry, tacky gums, sunken eyes, lethargy, and loss of appetite. If your cat hasn’t had anything to drink or eat in 24 hours, or if they are vomiting or have diarrhea, call your vet immediately. Dehydration can cause kidney damage fast. Do not wait.
“A cat that won’t drink is a cat that needs your help, not your worry. Small changes to their water and food can make a huge difference.”
Make Water a Game (Especially for Active Cats)
Some cats just need a little fun. Try placing multiple water bowls around the house, especially in places they like to hang out. A dripping faucet can be irresistible. You can also try a water fountain with a stream, many cats love to paw at the moving water. If your cat is active and you take them outside, make sure they have access to fresh water on the go.

If they resist, stop and try a different method.
If you have tried all of these tips and your cat still refuses to drink, please see your veterinarian. There may be an underlying medical issue like kidney disease, diabetes, or a dental problem. Your vet can run tests and may need to give subcutaneous fluids to rehydrate them quickly. You are doing a great job by noticing the problem early. Keep trying, and be patient. Your cat will thank you.
