I saw this and found it interesting thought I would share with you all!


US researchers on Thursday unveiled the secret of how cats lap water or milk with such elegance, a phenomenon that happens so fast it cannot be followed by human eyes.
Cats are among the many species that, unlike humans, cannot close their mouths and create suction.
With help from from high-speed video taken of a felines lapping liquid, researchers at the Massachusetts Institute of Technology (MIT) and Princeton University found that household cats and larger felines like tigers balance gravity and inertia as they imbibe liquids.
The research will appear in the November 12 issue of the journal Science.
Scientists already knew that when cats insert their tongue into a bowl of liquid, the top surface of the tongue touches the liquid first, then the tip curves like a letter J to form a sort of ladle.
This was first observed by an MIT engineer, who filmed a cat lapping liquid in 1940.
However by studying the images researchers have now determined that there is no ladling effect, but instead the cat's tongue darts in and out so quickly that the action forms a column of liquid.
"Cats, unlike dogs, aren't dipping their tongues into the liquid like ladles after all," read a statement from the MIT Department of Civil and Environmental Engineering.
Instead, the smooth tip of cat's tongue "barely brushes the surface of the liquid before the cat rapidly draws its tongue back up.
"As it does so, a column of milk forms between the moving tongue and the liquid's surface. The cat then closes its mouth, pinching off the top of the column for a nice drink, while keeping its chin dry."
The liquid column "is created by a delicate balance between gravity, which pulls the liquid back to the bowl, and inertia, which in physics, refers to the tendency of the liquid or any matter, to continue moving in a direction unless another force interferes."
The cat "instinctively knows just how quickly to lap in order to balance these two forces, and just when to close its mouth. If it waits another fraction of a second, the force of gravity will overtake inertia, causing the column to break, the liquid to fall back into the bowl, and the cat's tongue to come up empty."
Cats average about four laps per second, with each lap bringing in about 0.1 milliliters of liquid, the researchers said, adding that larger felines lap at a slower pace.

YouTube - Target commercial - dog digging a hole in water
ha ha ha...does she really? That is hillarious!

Both Kokka and Hibou lap at the water, but there is nothing graceful about and certainly not much of a column! The water splashes everywhere! Table, floor, me, her face, back and yes, her chin gets wet too!

One of my old cats dip the dip and lick method. She'd dip her paw into my glass, then lick her paw dry...this is the only way this cat, Absolut, drank!

YES!!! Well you may think its funny!! lol Its getting to be quite the challenge here! SoBe will drink from her paw sometimes if the water isn't filled to the brim which usually isnt because Snuffie is always in it up to her elbows!
She will wake me at 6am with soaking wet paws and legs..she's got it on the back of her head and neck, her butt, its everywhere! I've tried every shape, color and material (stainless steel, tupperware, plastic, pyrex, ceramic) of container I have...I've tried several different water depensers except the one that looks like a "Sorry" peg,,,not sure how to explain it. I'm planning on getting them one reluctently,,I know its not gonna work but stepping in cold water in your sock feet in the kitchen isn't so much fun anymore. lol
But yeah, when I saw that target commercial I immediatley asked Snuffie how she got on TV!!!!! :LOL::LOL:

:LOL::LOL::LOL:

Now Kokka does that with her food kind of...After she finishes eating her wet food (usually off of a small plate) she paws at the ground around the plate sweeping up all the bits she has flung about...basically the same action they use in the litter box!
It's the strangest thing.
I appreciate the clean up help mind you.

Now can some one tell me what evolutionary throwback behaviour this might stem from?
Do cats bury their leftovers in the wild?
