Cats know the names of their friends

Japanese scientists conducted experiments with cats and stated that they know the nicknames of other pets - this was indicated by the manifestation of the deceived expectation effect in the behavior of animals. The cats were shown photographs of familiar animals, while simultaneously calling out their nicknames: real or invented. In the second case, the pets looked at the photo longer. According to them, cats associate animals with their names. When they do not match, pets are surprised - this reaction is expressed in a longer viewing of the image.
