How cats drink! They are so smart... they've found the perfect lapping speed to maximize liquid intake!

Quote:
What happens is that the cat darts its tongue, curving the upper side downward so that the tip lightly touches the surface of the water.

The tongue is then pulled upward at high speed, drawing a column of water behind it.

Just at the moment that gravity finally overcomes the rush of the water and starts to pull the column down — snap! The cat’s jaws have closed over the jet of water and swallowed it.

The cat laps four times a second — too fast for the human eye to see anything but a blur — and its tongue moves at a speed of one meter per second.

Being engineers, the cat-lapping team next tested its findings with a machine that mimicked a cat’s tongue, using a glass disk at the end of a piston to serve as the tip. After calculating things like the Froude number and the aspect ratio, they were able to figure out how fast a cat should lap to get the greatest amount of water into its mouth. The cats, it turns out, were way ahead of them — they lap at just that speed.


More in the article (and a sort of awesome video interview with the scientists).

My cat drinks by dipping his paw in the water dish and then licking the water off of his paw. Apparently he doesn't have the smart cat gene.

Mine does that sometimes, out of cups. She usually refuses to drink from her bowl at all, though, and makes me turn on the faucet for her. Then she drinks so much she throws up.

I wish she had to smart cat gene.
