Here's a fact that surprises a lot of cat owners: cats are genuinely bad at drinking water. They evolved from desert animals and are wired to get most of their moisture from food — which is a problem when they're eating dry kibble from a bowl they can't be bothered visiting. Chronic under-hydration is one of the most common (and preventable) cat health issues.
Why Cats Don't Drink Enough
A cat's thirst drive is weak, and a still bowl of water just isn't appealing to them. Many cats also dislike water near their food, or in a spot that feels exposed. The result: they sip far less than they should, especially on a dry-food diet.
Why It Matters
Long-term dehydration puts strain on the kidneys and bladder and is linked to urinary tract problems and crystals — painful, serious, and expensive at the vet. Getting more water into your cat is one of the easiest wins for their long-term health.
Why Water Fountains Work
Cats are instinctively drawn to moving water — it reads as fresh and safe (think running streams, not stagnant puddles). A fountain keeps water circulating and filtered, and most cats drink noticeably more from one than from a bowl. Bonus: filtered, oxygenated water tastes better to them too.
Other Easy Hydration Wins
- Add wet food to the diet — it's mostly moisture.
- Offer multiple water stations around the house, away from food and litter.
- Keep it fresh — cats are fussy about stale water.

Cat Hydration FAQs
How much water should a cat drink?
Roughly 50ml per kg of body weight per day, including moisture from food. A 4kg cat needs around 200ml daily.
Why a fountain instead of a bowl?
Cats prefer moving water and tend to drink more from a fountain. The filter also keeps it fresh, which fussy cats appreciate.
How often should I clean it?
Rinse and refill every few days, do a full clean weekly, and change the filter as recommended — a clean fountain is one your cat will keep using.
