When it comes to cats and physics, most people don’t get much further than Erwin Schrödinger and his gedankenexperiment involving a feline locked in a box. But research from Saho Takagi and her colleagues at Kyoto University in Japan suggests that cats don’t just star in physics thought experiments, they may also have an innate understanding of (some of) the physics, too.

We’re not suggesting that SpaceX or Blue Origin is looking to hire feline rocket scientists any time soon, Or that the cats know what to do with Schrödinger’s wave function. But Takagi’s study provides evidence that our furry little friends might have a better understanding of causal relationships than previously thought, and they may also have a “rudimentary understanding of gravity.”

The study involved 30 Japanese cats—eight house pets and 22 residents of cat cafes. The researchers tested the cats using a plastic box containing some iron balls. Normally the balls were free to rattle around in the container, falling out when the box was inverted. But on the opposite side to the box’s open end, they added an electromagnet. When turned on, the magnet stopped the balls from rattling or falling out.
