How to Get Your Cat to Drink More Water (and Why It Really Matters)

You fill the bowl, your cat strolls past it without a glance, and then you catch them drinking out of your glass, the bathroom sink, or a puddle on the balcony. If your cat seems weirdly uninterested in their actual water bowl, you’re not imagining it — and it’s worth paying attention to, because cats are quietly prone to dehydration.

Here’s why that happens, the signs to watch for, and nine simple changes that get most cats drinking more.

Why do cats barely drink water?

Blame their ancestry. Cats descended from desert animals and evolved to get most of their moisture from prey, so they have a naturally low thirst drive. In the wild that works fine. On a diet of dry kibble, it’s a problem — many house cats run mildly under-hydrated, which over time strains the kidneys and bladder and contributes to urinary issues. A few feline quirks make it worse:

• They dislike water next to food or litter. In the wild, water near a kill (or waste) could mean contamination, so instinct tells them to keep some distance.
• Whisker fatigue. Deep, narrow bowls press on their sensitive whiskers with every sip. Many cats would rather under-drink than deal with it.
• They like it fresh and moving. Still water that’s sat all day reads as “stale.” A faucet or fountain reads as “fresh and safe.”

Signs your cat might be dehydrated

Worth knowing so you can catch it early. Gently lift the skin between the shoulder blades — if it doesn’t spring back quickly, that’s a red flag. Other signs include tacky or dry gums, low energy, sunken eyes, reduced appetite, constipation, or peeing noticeably less. If you spot these, call your vet — dehydration can point to something that needs treatment.

9 simple ways to get your cat drinking more

1. Add a pet water fountain

This is the single biggest win for most cats. Moving water is fresher, better oxygenated, and taps straight into that instinct to drink from a flowing source. Lots of cats who ignore a bowl will happily drink from a fountain — a quiet ceramic one blends into the kitchen and is easy to keep clean.

Prefer a larger-capacity option? The Automatic Electric Pet Water Fountain ($47.99) holds more water between refills — handy for multi-cat homes.

2. Switch to a wide, shallow bowl

If a fountain isn’t your thing, the next best fix is a bowl that doesn’t crush your cat’s whiskers. A wide, shallow ceramic bowl lets them drink without anything brushing their face — and ceramic doesn’t hold odors the way plastic can.

3. Move the water away from food and litter

Don’t cluster the water bowl right next to the food dish or anywhere near the litter box. Give it its own spot — ideally a different room. It sounds small, but it lines up with your cat’s instincts and often makes an immediate difference.

4. Offer several water stations

Cats drink more when water is easy to stumble upon. Put a couple of extra bowls or a fountain in the rooms where your cat actually hangs out, so a drink is never more than a few steps away.

5. Add wet food

Wet food is roughly 70–80% water, so even swapping one meal a day from dry to wet meaningfully boosts your cat’s total moisture intake. If your cat is dry-food-only, this is one of the easiest hydration upgrades there is.

6. Try a different bowl material

Some cats dislike the smell or taste that plastic bowls can pick up over time. Glass, ceramic, or stainless steel are cleaner-tasting and easier to keep fresh. A tilted, elevated bowl also makes the angle more comfortable for senior cats.

7. Keep it fresh and clean

Change the water daily and wash the bowl often — a slimy film (that’s biofilm) builds up fast and puts cats off. Fountains help here too, since the filter and circulation keep things fresher between cleanings.

8. Flavor it (gently)

A splash of water from a tuna can, a little low-sodium plain broth, or a few ice cubes to bat around can tempt a reluctant drinker. Just avoid anything with onion or garlic, which are toxic to cats.

9. Cover hydration on the go

Vet visits, car trips, and warm-weather outings are exactly when cats skip water. A portable leak-proof bottle with a built-in bowl makes it easy to offer a drink anywhere.

Frequently asked questions

How much water should a cat drink per day?

Roughly 3.5–4.5 ounces per 5 pounds of body weight daily — but that includes the moisture in their food. A cat on wet food will drink far less from the bowl than one on dry food, and that’s normal.

Do cat water fountains really work?

For most cats, yes. The movement and fresher taste are genuinely more appealing than a still bowl, and many owners see their cat drinking more within days of switching.

Why does my cat prefer the sink or my glass?

It’s usually about freshness and movement, plus keeping water away from their food. A fountain gives them that same “running, fresh” appeal in their own space.

Is wet food enough to keep my cat hydrated?

It goes a long way — wet food’s high moisture content covers a big chunk of a cat’s needs. Still offer fresh water too, especially in warm weather.

My cat suddenly started drinking a lot more. Should I worry?

A sudden, marked change in drinking — up or down — is worth a vet visit. Increased thirst can be an early sign of kidney disease, diabetes, or thyroid issues, so it’s best checked.

When to call your vet

Encouraging water is great preventive care, but it’s not a substitute for a check-up. See your vet if your cat shows signs of dehydration, suddenly drinks much more or much less than usual, strains in the litter box, or stops eating. Those can signal urinary or kidney problems that need real treatment.
