Why Does My Cat Drink From the Faucet? Water Preferences Explained
You turn on the faucet, and your cat appears from nowhere. It hops on the sink, sticks out its tongue and laps up the stream. The water bowl sits nearby, full and ignored. This is common, and has good reasons.
Why cats like running water
- Instinct. In nature, still water can be contaminated, while moving water is usually safer. Cats may be drawn to flow.
- Freshness. Tap water is cool and oxygenated.
- Sensory appeal. Movement, sound and reflection attract attention.
- Whisker comfort. A narrow bowl can touch the whiskers, which some cats dislike.
- Bowl position. Water near food or the litter box may be unappealing.
- Plastic taste. Plastic bowls hold odors.
- Attention. If you respond, the cat may repeat.
- Fun. Many cats like to play with dripping water. See why do cats paw at water.
Why drinking matters
Cats evolved to get most water from prey, and have a low thirst drive. Cats that eat dry food need to drink more. Low water intake is linked to urinary problems and kidney disease. See how to get a cat to drink more water, feline idiopathic cystitis and chronic kidney disease in cats.
Offer better options
- A water fountain. Circulating water tempts many cats. See cat water fountains worth it.
- Wide, shallow bowls of ceramic, glass or stainless steel, which do not retain odor and do not touch whiskers.
- Several water stations, in quiet places, away from food and litter.
- Fresh water daily, with bowls washed regularly. See how to clean cat food bowls.
- Wet food, which adds moisture. See wet vs dry cat food.
- Ice cubes or a splash of water in food.
- A dripping tap, carefully used, if safe.
Clean fountains
Fountains need cleaning weekly, or biofilm builds up. Change filters. Pumps can be noisy, so some cats avoid them.
Faucet safety
- Never leave water running unattended, since cats can flood the home or slip.
- Check water temperature, to avoid scalds.
- Keep chemicals, cleaning products and razors away from sinks. See cat safe cleaning products.
- Clean sinks after use.
- Be careful with lead pipes or poor quality water. Check local water advice.
Tap water or bottled?
Most tap water is fine. If water has strong chlorine or mineral taste, a filter may help. Distilled water is not necessary for healthy cats.
How much should a cat drink?
A rough guide is about 3.5 to 4.5 ounces of water per 5 pounds of body weight per day, including the moisture in food. A cat on wet food may drink very little from the bowl. Cats on dry food drink more.
When drinking is a problem
See a vet if your cat:
- Drinks much more than usual, or constantly seeks water.
- Urinates large amounts, or has accidents.
- Loses weight, or appetite changes.
- Shows lethargy or vomiting.
These can signal diabetes, kidney disease, hyperthyroidism or infection. See increased thirst in cats, diabetes in cats and hyperthyroidism in cats.
Drinking too little
Signs of dehydration include dry gums, sunken eyes and lethargy. See cat dehydration signs and treatment.
Senior cats
Older cats may drink more, or find it harder to reach bowls. Provide easy access. See senior cat home modifications.
Training
If you do not want the cat on the counter, provide a fountain and other water sources, and reward it for using them. See how to keep a cat off kitchen counters.
Making water exciting
Try different bowls, locations and temperatures. Place bowls by favorite resting spots. Some cats like a bowl on a raised stand. Rotate and see what works.
Frequently asked questions
Should I let my cat drink from the tap? If the faucet is clean and the cat is safe, yes. Is a fountain better than a bowl? Many cats drink more from fountains, so try one. How often should I wash the bowl? Daily for bowls, weekly for fountains. Why does my cat ignore water in the kitchen but drink in the bathroom? Location matters, so try several places.
Experiment and observe
Try two or three bowls in different places, and watch what your cat prefers. Measure how much disappears over a day, if you can. Cats that drink little from bowls but eat wet food may be perfectly hydrated. A cat on dry food needs more encouragement. If you cannot tell, ask your vet to assess hydration at the next visit.
When to see a vet
See a vet if drinking changes sharply. Use the US vet directory to find a clinic.
