How Do Cats Drink Water? The Surprising Science Behind Feline Hydration

Many cat lovers have watched their favorite feline drink water and wondered: How does a cat get enough water when their tongue barely seems to touch the surface? The answer lies in a fascinating drinking technique that combines speed, precision, and physics.

How Do Cats Drink Water?

Cats drink by lightly touching the surface of the water with the tip of their tongue and then quickly pulling it back. As the tongue retracts, it pulls a small column of water upward. Before gravity can pull the water back into the bowl, cats close their mouth and capture the top of the water column. Next, they simply swallow and repeat.

Why Do Cats Drink This Way?

Cats likely evolved this method to drink efficiently while minimizing the amount of water that splashes around their face and whiskers. Research by the Massachusetts Institute of Technology calculated at which speed cats would have to stick their tongue into the water to get the optimal amount of water. Next, footage taken with high-speed cameras revealed that cats instinctively use a lapping speed that maximizes the amount of water they can capture before gravity causes the water column to collapse. In other words, cats are amazing physicists.

How Is Cat Drinking Different from Dog Drinking?

The biggest difference is how the tongue interacts with the water. A cat’s way of drinking is more delicate while dogs… well, dogs will be dogs.

CATS

Don’t curl their tongue like a spoon.
Barely touch the water with the tip of the tongue.
Pull water upward using inertia.
Rely on precise timing.
Drink relatively neatly.

DOGS

Curl their tongue backward like a ladle.
Dunk their tongue deep into the water.
Scoop large amounts of water into their mouths, as well as benefiting from inertia.
Rely more on tongue volume than precise timing.
Create more splashing and mess.

Why Do Dogs Make More of a Mess When Drinking?

Dogs use a backward-curled tongue that acts like a ladle, lifting water into the mouth, as well as making use of inertia to pull up a column of water like cats do. This method is effective for consuming large amounts of water quickly, but it also causes significant splashing as dogs stick their tongue into the water much deeper than cats.

Do Big Cats Drink the Same Way?

Yes. Lions, tigers, leopards and other big cats use the same basic drinking mechanism as domestic cats. The main difference is size. Larger cats have bigger tongues and create larger water columns, allowing them to lap at a slower rate while still drinking efficiently.

Frequently Asked Questions

Do cats scoop water with their tongues?

No. Cats do not scoop water like dogs. Instead, they touch the water surface with the tip of their tongue, pull upward, and capture a rising column of water.
