Why Is My Cat Not Drinking Enough Water

August 6, 2026

Cats are animals that originally obtained much of their hydration directly from their prey, which led them to evolve with a less pronounced thirst instinct than dogs. This means that many cats, especially those fed dry kibble, simply don't drink enough on their own — and that can have real consequences for their health.

Why cats naturally drink so little water

Unlike dogs, cats are descended from desert animals that got most of their hydration from the high-water content prey they hunted. This instinct remains today: their thirst mechanism is less sensitive, so a cat can be mildly dehydrated without showing obvious signs of wanting to drink more.

Risks of insufficient hydration

Chronically low hydration is directly linked to kidney and urinary tract problems, two of the most common health conditions in adult and senior cats. Maintaining good water intake throughout your cat's life is one of the most effective and least expensive preventive measures available.

How to tell if your cat is well-hydrated

Urine should not have an extremely concentrated odor.
Gums should look moist and pink, not sticky.
Skin should quickly return to its original position when gently pinched.
Normal energy level, without unexplained lethargy.

Real solutions to get your cat to drink more

Moving water sources: Cats have an instinctive preference for running water over static water in a bowl; an electric fountain like AguaViva takes advantage of exactly that instinct.
Multiple water stations: Place water bowls in different areas of the house, not just next to the food dish.
Wet food: Incorporating wet food, even partially, significantly increases total water intake.
Always fresh water: Change it daily; stagnant water is less appealing to a cat's sense of smell.

Frequently asked questions

Is it normal for my cat to prefer drinking from the faucet?
Yes, it's the same instinct towards moving water; an electric fountain can replicate that preference without you having to leave the faucet running.

How much water should a cat drink per day?
Approximately 50 ml per kilogram of body weight, although this varies depending on whether their diet is dry or wet.

Should I worry if my cat hardly drinks visible water?
If their diet is primarily wet, it's normal for them to drink less water directly; if it's 100% dry and they barely drink, it's worth implementing the solutions in this guide.
