A study published in the journal Scientific Reports on April 4, 2019, challenges the common belief that cats are deaf to their own names. Researchers from Japan—Atsuko Saito, Kazutaka Shinozuka, Yuki Ito, and Toshikazu Hasegawa—conducted experiments to determine if domestic cats can distinguish human utterances, such as their own names, from common names or names of other cats they live with. The method used is called the habituation-dishabituation technique, which involves playing a sequence of four ordinary words and then saying the cat's name. If the cat reacts more strongly to the last word, it suggests the animal noticed the difference. The study found that cats recognize their own names by distinguishing individual sounds, or phonemes, rather than just the tone or pitch of the voice. The reaction to their name is subtle, often limited to a slight movement of the ears or head—only a few millimeters. However, cats living in cat cafes did not distinguish their names from those of other cats, unlike cats in home environments. The researchers observed that when cats were used to hearing sequences of names, they showed a significant response when their own name was spoken, even when the names were said by strangers. The researchers classified the cats’ responses into two types: communicative responses, such as meowing or tail movement, and orientational responses, like ear or head movement. In all the experiments, more than half of the cats reacted to the sound by moving their ears or heads slightly. Only a small percentage—less than 10%—showed more noticeable behaviors like meowing or moving their tails. These subtle movements, barely visible, suggest that cats can detect phonemic differences in human speech. This finding aligns with previous research by the same team, which showed that cats respond to their owners’ voices through small movements, not through vocalizations or tail movement. The study also revealed an exception: cats in Japanese cat cafes did not distinguish their own names from those of other cats living with them. Researchers suggest that this may be due to the social environment of cafes, where different people may say the names with varying intonations or without offering consistent rewards. The study changes how we understand how cats process sound. Even if a cat seems to ignore its name, it may still be reacting to it with a tiny ear or head movement before the name is fully spoken. This ability to distinguish sounds is more advanced than many owners realize. However, one question remains: do cats associate their name with their identity, or do they simply recognize it as a signal for something like food, affection, or a visit to the vet?
