What Is Your Cat Thinking?

It’s hard to say:

Dogs have lived with us for as many as 30,000 years—20,000 years longer than cats. More than any other animal on the planet, dogs are tuned in to the “human radio frequency”—the broadcast of our feelings and desires. Indeed, we may be the only station dogs listen to.

Cats, on the other hand, can tune us in if they want to (that’s why they pass the pointing test as well as dogs), but they don’t hang on our every word like dogs do. They’re surfing other channels on the dial. And that’s ultimately what makes them so hard to study. Cats, as any owner knows, are highly intelligent beings. But to science, their minds may forever be a black box.

Still, there may be hope. As scientists begin to experiment with new ways to study animal intelligence—from eye-tracking technology to fMRI machines—they may yet find a way to peek inside the feline mind.
