Well, there actually is something scientific to that kind of movie scenario. According to an article shared by our favorite helmsman on the Star Ship Enterprise George Takei, by HigherPerspective.com, cats and other sensitive animals like dogs or deer, can see certain kinds of light, such as UV (ultraviolet) light that we humans simply can’t see. This means that more sensitive animals are seeing a lot of things in the world that we aren’t, like patterns on flowers and in the fur of other animals. These patterns, visible through UV light are completely invisible to the human eye which does not see ultraviolet rays.
A human might have trouble seeing a polar bear in the snow, while these other more sensitive animals would have no trouble spotting a big white bear in the snow no matter how still it might be. Why? Sixth sense? No. These animals are actually able to see a polar bear in the snow because they see ultraviolet light, which would reflect off the snow, while the white fur of a polar bear would absorb the UV light. This is what makes an animal like a polar bear visible to a deer or your house cat, and now we are learning that this kind of animal super vision might be more common than science had realized.
So next time your cat reacts as if it sees something in the room while you see nothing there, you might want to consider that your cat is picking up on real things that are are invisible to your human eyes.
