I just read at Yahoo main page about a group of US researcher. They did research on how cats drink. Way back in 1940, a man already videotaped a cat when she was lapping a liquid. He found out that the tip of cat's tounge touch the liquid and then, the tounge form a ladle where the liquid will fall into and when the cat pull in her tounge, the liquid goes inside the throat.
However recent research tell otherwise. There's no ladle effect. In fact, there are the balance of inertia and gravity that the cats or any other felines naturally learnt from don't know where. It is just their nature. And the way they drink is different from dogs. Cats never dip in their tounge in the liquid.
The tip of the tongue just touch the liquid surface and the balance of gravity it creates when it looks like lapping can form a column of liquid. And this column of liquid is maintained by inertia. And wonderfully, they just know what is the speed to lap if they are to maintain drinking! How smart they are, aren't they?
The average of cat's lapping is 4 laps per second which bring in 0.1ml per lap. Bigger feline laps at slower pace.
