The Silent Hydration Crisis: Why Your Cat’s Water Bowl Isn’t Enough
You fill their bowl every day, but have you ever actually seen your cat drink? Unlike dogs, who happily lap up water, cats are stealthy hydrators—or sometimes, not hydrating enough.
Cats evolved from desert-dwelling ancestors, meaning they’re wired to get most of their moisture from prey (Peterson, 2012). But since modern cats eat dry kibble, many live in a state of mild dehydration without their owners realizing it.
Left unchecked, chronic dehydration can lead to urinary tract infections, kidney disease, and bladder stones (Buffington et al., 2014). So how do you know if your cat is drinking enough? And what can you do to help?
How Much Water Does Your Cat Really Need?
A general rule? Cats need 50–65 ml of water per kilogram of body weight daily (National Research Council, 2006). But since most cats don’t drink from a bowl like dogs, their intake often falls short.
Signs Your Cat Isn’t Drinking Enough
-
Dry, sticky gums (lift their lip—gums should be slick, not tacky)
-
Loss of skin elasticity (gently pinch their scruff—if it doesn’t snap back quickly, they may be dehydrated)
-
Concentrated, strong-smelling urine (healthy urine should be pale yellow)
-
Lethargy or reduced appetite
5 Vet-Approved Ways to Get Your Cat to Drink More
1. Switch to Wet Food
Wet food is 70–80% water, while dry kibble is only 10% (Zoran, 2002). Even mixing a little water into their meals can boost hydration.
2. Try a Cat Water Fountain
Cats prefer running water—it’s instinctual. A fountain can encourage drinking (though some cats still prefer your glass of water… because of course).
3. Place Multiple Water Bowls Around the House
Ever notice your cat drinks from your cup but ignores their bowl? Place stainless steel or ceramic bowls (plastic can harbor bacteria) in quiet, safe spots.
4. Flavor the Water (Safely!)
A splash of low-sodium chicken broth (no onions or garlic!) or tuna juice can entice picky drinkers.
5. Monitor Their Intake
Track how much they drink daily. If you’re concerned, your vet can run bloodwork or a urinalysis to check kidney function.
Final Thought: Small Changes, Big Impact
Cats are masters at hiding discomfort, so proactive hydration habits matter. A simple switch to wet food, a new water fountain, or even an extra bowl in their favourite nap spot can make all the difference.
