Almost any cat owner will testify to the feline's apparent indifference to humans when we call their names.

But according to a recent study, cats do recognize their names, or at least that we are indeed addressing them.

It's just that they still may not respond.

I think cats associated sounds of their names with some rewards or punishments.

Atuko Saito, a behavioral scientist at Sofia University in Tokyo.

Saito previously demonstrated that cats recognize their owner's voices. In the new work, she and colleagues investigated the reactions of cats to hearing humans say their names.

The study included 78 cats from Japanese households and from a cat cafe, a business where patrons can interact with felines.

Saito and her colleagues had owners say four words that sounded similar to their cat's names

until the animals habituated to those words and stopped responding.

Next, the owners said the feline's actual names.

And indeed, the cats had more pronounced responses, moving their ears, heads, tails, or meowing than they did to similar words or to other cats' names.

The study is in the journal Scientific Reports. The researchers also had people unfamiliar to the cats

speak the names. Although the feline's responses were less prominent than when their owners called them,

they still appeared to recognize the words when spoken by strangers. But does that mean cats know they are being called by name?

There is no evidence that cats have the ability to recognize themselves like us.

So the recognition about their names is different from ours.
