Despite the fact that cats find it difficult to distinguish fine patterns like humans do, it turns out, that they can actually distinguish some optical illusions as this video demonstrates.
This cat is responding to what’s known as the Rotating Snake Illusion, or peripheral drift, which sees the shapes start to moves and slither when you rapidly look to the edge while blinking.
Turns out that cats can actually determine the difference between random shapes and shapes aligned in a pattern. Looks like they’re smarter than we thought. [r/videos]
