To get your cat to drink more water, make hydration effortless and appealing: offer a flowing water fountain, add wet or water-topped food to their diet, and place several clean bowls away from food and litter. Cats evolved from desert animals and have a naturally weak thirst drive, so small changes to how you offer water often matter more than nagging them to drink.
Why hydration matters more than most owners realize
Water does quiet, essential work inside your cat. Because cats instinctively drink less than they should, low intake is one of the most common issues veterinarians flag, and it tends to build slowly rather than announce itself.
- Urinary tract health: Diluted urine is less likely to form the crystals and irritation associated with feline lower urinary tract disease (FLUTD). More water usually means your cat urinates more often, flushing the system.
- Kidney support: The kidneys filter constantly, and steady hydration eases that workload. This matters especially for senior cats, who are more prone to kidney concerns.
- Digestion and energy: Adequate water supports smoother digestion and helps prevent the sluggishness and constipation that can follow chronic under-drinking.
None of this replaces veterinary care, but daily hydration is one of the few levers you fully control at home.
Signs your cat may not be drinking enough
Dehydration is easy to miss because cats hide discomfort well. Watch for these clues:
- Skin tent test: Gently lift the skin between the shoulder blades. It should snap back instantly; if it settles slowly, hydration may be low.
- Tacky or dry gums instead of slick, moist ones.
- Sunken-looking eyes, lethargy, or noticeably less energy.
- Small, hard stools or fewer trips to the litter box.
If you see these signs, or your cat suddenly drinks far more or far less than usual, call your veterinarian. Sudden changes can signal an underlying condition that hydration alone won't fix.
How to get your cat to drink more water
Here is where small, practical changes pay off. You don't need all of these at once, so start with running water and go from there.
1. Give them running water with a fountain
Many cats instinctively prefer moving water over a still bowl, likely because in the wild, flowing water is fresher and safer than a stagnant puddle. A fountain also keeps water aerated, filtered, and enticing throughout the day. For a cordless setup you can place anywhere without a wire across the floor, the Wireless Smart Cat Water Fountain holds a large reservoir and keeps water moving. If your cat is easily startled by noise, a gentle, quiet stream like the Catwell Flowing Water Fountain can be less intimidating for first-time fountain drinkers. Prefer a hygienic, easy-to-clean drinking surface? The stainless-steel Steelspring Cordless Cat Water Fountain resists the biofilm that builds up on plastic.
2. Rethink the bowl (and where it lives)
If a fountain isn't an option yet, upgrade the humble bowl:
- Go wide and shallow. Deep, narrow bowls press on a cat's sensitive whiskers, and "whisker fatigue" can make some cats avoid drinking.
- Choose ceramic or stainless steel over plastic, which can hold odors and harbor bacteria.
- Separate water from food and litter. Cats instinctively avoid drinking near their food source or bathroom. Place bowls in a different room entirely.
- Offer multiple stations. Two or three water spots around the home give your cat easy access wherever they roam.
- Keep it fresh. Change water at least once daily and wash bowls often.
3. Add moisture through food
Diet is one of the most powerful hydration tools. Dry kibble is roughly 10% water, while wet food is around 70-80%. Mixing in or switching to wet food dramatically raises daily intake without your cat "trying" at all. You can also stir a tablespoon of water or a plain, low-sodium, onion- and garlic-free broth into meals to make them soupier.
4. Keep water within reach on the go
Travel, vet visits, and carrier time are when cats skip water most. A portable option like the Antler Portable Cat Water Bottle lets you offer a fresh sip one-handed, so a nervous trip doesn't turn into a dehydrated one.
Fountain vs. bowl: which should you choose?
A bowl is cheap, simple, and fine for cats who already drink well, but water sits still, warms up, and collects dust between refills. A fountain keeps water moving and filtered, appeals to cats' preference for running water, and typically encourages more frequent drinking with less daily maintenance. For a picky or under-drinking cat, a fountain is usually the single highest-impact change you can make. If you go the fountain route, still clean it on the schedule the manufacturer recommends, since even filtered water needs regular upkeep.
How much water does a cat actually need?
As a general guideline, a healthy cat needs roughly 3.5 to 4.5 ounces of water per 5 pounds of body weight per day, including moisture from food. That means a 10-pound cat on wet food may drink very little from the bowl and still be well hydrated, while a kibble-only cat has to make up the difference by drinking. Use this as a rough benchmark, not a strict rule, and let your vet weigh in for cats with medical conditions.
Learning how to get your cat to drink more water usually comes down to removing friction: fresh, moving water they enjoy, thoughtful bowl placement, and more moisture in the diet. Pick one change this week, watch how your cat responds, and build from there. Their kidneys and urinary tract will quietly thank you for years.
