Hey Kitty! Yes, you. A new study suggests household cats can respond to the sound of their own names.
No surprise to you or most cat owners, right? But Japanese scientists said Thursday that they91ÂãÁÄÊÓƵ™ve provided the first experimental evidence that cats can distinguish between words that we people say.
So you91ÂãÁÄÊÓƵ™re kind of like dogs, whose communication with people has been studied a lot more, and who91ÂãÁÄÊÓƵ™ve been shown to recognize hundreds of words if they91ÂãÁÄÊÓƵ™re highly trained. Sorry if the comparison offends you, Kitty.
Atsuko Saito of Sophia University in Tokyo says there91ÂãÁÄÊÓƵ™s no evidence cats actually attach meaning to our words, not even their own names. Instead, they91ÂãÁÄÊÓƵ™ve learned that when they hear their names they often get rewards like food or play, or something bad like a trip to the vet. And they hear their names a lot. So the sound of it becomes special, even if they don91ÂãÁÄÊÓƵ™t really understand it refers to their identity.
Saito and colleagues describe the results of their research in the journal Scientific Reports. In four experiments with 16 to 34 animals, each cat heard a recording of its owner91ÂãÁÄÊÓƵ™s voice, or another person91ÂãÁÄÊÓƵ™s voice, that slowly recited a list of four nouns or other cat91ÂãÁÄÊÓƵ™s names, followed by the cat91ÂãÁÄÊÓƵ™s own name.

Many cats initially reacted 91ÂãÁÄÊÓƵ” such as by moving their heads, ears or tails 91ÂãÁÄÊÓƵ” but gradually lost interest as the words were read. The crucial question was whether they91ÂãÁÄÊÓƵ™d respond more to their name.
Sure enough, on average, these cats perked up when they heard their own name.
Kristyn Vitale, who studies cat behaviour and the cat-human bond at Oregon State University in Corvallis but didn91ÂãÁÄÊÓƵ™t participate in the new work, said the results 91ÂãÁÄÊÓƵœmake complete sense to me.91ÂãÁÄÊÓƵ
Vitale, who said she has trained cats to respond to verbal commands, agreed that the new results don91ÂãÁÄÊÓƵ™t mean that cats assign a sense of self to their names. It91ÂãÁÄÊÓƵ™s more like being trained to recognize a sound, she said.
Monique Udell, who also studies animal behaviour at Oregon State, said the study shows 91ÂãÁÄÊÓƵœcats are paying attention to you, what you say and what you do, and they91ÂãÁÄÊÓƵ™re learning from it.91ÂãÁÄÊÓƵ
