Living with cats can feel like a mystery. You talk to them, but you're never quite sure what they're thinking. Do cats understand words? Can cats understand humans? If you wonder what your kitty hears when you talk to them, you're not alone. Let's see what science has to say about this feline enigma.

Do Cats Understand Words?

If your cat doesn't come when you call them, it doesn't necessarily mean they're ignoring you. It could be that they're reacting nonverbally and you just aren't noticing it. Cats lack the cognitive skills to interpret human language, but they recognize when you talk to them. To put it another way, cats comprehend human language in the same way that we understand meowing. It's similar to how you interpret your cat's language by "reading" how they arch their back or swish their tail.

Cats may not process human language in the same way that humans do, but studies show that cats recognize and, in some cases respond to, human vocalizations, gestures and expressions — depending on whether they feel like it, of course.

Can Cats Understand Humans?

Scientists have only scraped the surface in terms of understanding feline cognition. However, in the past several years, researchers have made exciting discoveries about the cat brain.

In an article published by Animal Cognition, researchers noted that the cats they studied responded when their pet parents said their names. The cats mostly responded to their humans' voices through orienting behavior, such as ear movement and head movement, rather than through communicative behavior, like vocalization and tail movement.

You can do a similar study of your own at home: Closely observe your cat while you say their name. They may pivot their ears, tilt their head to the side while looking at you or both. A chatty cat might respond vocally, but as this study shows, cats generally use nonverbal communication to respond to their human.
