    Cats drink more effeciently than dogs

    The results are in. Scientists have proved that cats are better and more efficient than drinking than dogs.
     
    It has been one of the age old questions throughout time but a team of scientists, reequipped with high tech slow motion cameras have proved that cats are much more efficient that dogs when drinking water. The cameras were used to measure the both animal’s drinking habits.
     
    Being human and drinking is easy, you pick up a glass and pour the water in your mouth. For a dog and a cat, the art of drinking is more difficult. The tongue has to be used to “pick up” the water.
     
    What is also very interesting is a complete rethink into how exactly dogs drink. For years it was thought that their tounges were inverted backwards and they would scoop up the water. The Daily Mail try to explain the unique technique for both cats and dogs.
     
    “Researchers have found that instead of a ladle, the tongue acts as a sticky whip to which a stream of water will attach to and follow the tongue upwards.
     
    Just as gravity is about to kick in the dog snaps its mouth shut. 
    As for cats, their tongues work in the same way but far more delicately, lapping up water or milk around four times per second - too fast to see even with a high speed camera.”
     
    As a result of discovering this new technique, scientists were able to go in further and measure exactly how much animals drink and how much actually gets taken in. Cats take in more liquid and have less spillage than dogs. This makes them more efficient.

    The research was undertaken by the Massachusetts Institute of Technology, Virginia Tech and Princeton University in the USA

    Jeffrey Aristoff who worked on the project said that 'The amount of liquid available for the cat to capture each time it closes its mouth depends of the size and speed of the tongue,' 

    'Our research - the experimental measurements and theoretical predictions - suggests that the cat chooses the speed in order to maximise the amount of liquid ingested per lap.
     
    'This suggests that cats are smarter than many people think, at least when it comes to hydrodynamics.'
     
    The work began three-and-a-half years ago when MIT's Roman Stocker, who studies the fluid mechanics of the movements of ocean microbes, was watching his cat, Cutta Cutta, lap milk.
     
    'Science allows us to look at natural processes with a different eye and to understand how things work, even if that’s figuring out how my cat laps his breakfast,' said Professor Stocker.
     
    'It’s a job, but also a passion, and this project for me was a high point in teamwork and creativity.'
