Cats Know Your Feelings

If you spend a lot of time on the Internet, we know at least one thing: we all love cats. But that's what they think about us - it's a mystery. Compared to loyal dogs, cats with union jack cat collar seem to be very indifferent to the Affairs of man. But it turns out that our cats pay more attention than we think they would. Cats that we provide any kind of cat stuff seem to be able to say, when we are happy. In the new studies were able to obtain evidence that cats are sensitive to the emotions and gestures of the person.

Scientists from the Oakland University in Rochester, Michigan, studied 12 cats and their owners. They found that the cats had different behaviors when their owner smiled than when he frowned. When cats are faced with the smile of the owner, they showed more positive behavior purred, he was asked to hand. Also it was obvious that the cats tried to spend more time with the owner when he was smiling and not frowning.

The situation was completely different, when the cats left with strangers and not with their owners. They were equally positive regardless of, the person frowned or smiled. These results indicate that cats can understand a person's expression, and they develop this ability over a long period of time. That dogs can distinguish facial expression of the person has long been known. But for the first time, evidence shows that cats have the same ability.

Prior to this there had been only one research study to see whether cats can perceive human emotions. It was published in January 2015, and the results were mixed. But now scientists say that cats are much more in tune with human emotions than thought until now.
