With the same thirst, Micio draws from the bowl of water with surgical precision, Fido lapses in a voracious manner, overturning half of the contents on the ground. Dogs are more clumsy than cats even when it comes to drinking, and some American scientists have taken the trouble to explain why.

Feline sips. The study, presented in San Francisco during a meeting of the American Physical Society, is based on an earlier 2010 research, conducted by MIT, Virginia Tech and Princeton University, on the physics of cat sips. According to the old work, when they drink, the cats stretch their folded back tongue towards the top layer of water or milk, which they quickly retract, creating a column of liquid between the bowl and the moving tongue. This rising flow is drawn towards the cat's mouth at a speed of one meter per second, and before it can fall back due to gravity, the felines draw from its top with 4 swallows per second.

The Fido version. When Virginia Tech's bioengineers repeated their studies on dogs, analyzing high-speed footage of their drinks, they expected to find similar results, but this was not the case. While the cats lightly touch the surface of the water, the dogs immerse their tongues impetuously, raising a lot of splashes. While the water column of the cats is raised with a force equal to 2 times the gravity, the dogs create a force equal to 8 times the gravity.

Big dogs, big … lakes. Finally, if in the case of cats it is only the tip of the tongue to come into contact with the liquid, for dogs it is a large portion of the tongue to get wet: a fact that makes them particularly noisy and messy drinkers. As expected, the volume of water raised by a dog's tongue is proportional to its size: a San Bernardo will wet the kitchen floor much more than a dachshund.
