Science Confirms That Cats And Dogs Can See “Spirits” And Other Frequencies
It is simple, the scientific explanation is that cats and dogs can see UV light and some other rays, which human retinas do not have the ability to see.
It was previously believed that all mammals had eyes similar to humans, unable to see UV rays, but scientific evidence suggests that many mammals can instead.
A study conducted a few years ago by biologists at City University London, in the United Kingdom, provided evidence of this differential in sight between species.
This is what Pet MD has to offer.
Have you ever thought that your dog or your cat can see something that you can't? Well, according to a new study, if you did, you're right.
Can cats and dogs see spirits?
Cats, dogs and other mammals are thought to see ultraviolet light, which opens up a world different from what we see, the study explains.
UV light is the wavelength beyond light visible from red to violet that man can see.
Humans have a lens that blocks UV rays and prevents them from reaching the retina. It was previously believed that most mammals had lenses similar to humans.
Scientists have studied the lenses of dead mammals, including cats, dogs, monkeys, pandas, hedgehogs and ferrets.
Researching how much light went through the lens to reach the retina, they concluded that some mammals that were previously thought could not see UV can actually.
Humans are good at seeing detail, because they have high color-sensitive cells, or their cones, which produce high-quality images with just a small amount of light. By contrast, nocturnal animals have eyes that let in too much light, including ultraviolet light, though it may not serve any special purpose.
Ultimately, knowing that many animals have ultraviolet vision could provide a deeper understanding of why they behave the way they do. Or maybe your cat really is just crazy.
Here's how the world might look to a cat at night.
