We hope you enjoyed yesterday’s Plot Bunnies featuring our Cannibal Galaxy. This is the beginning of a new project that Dave Mornix and I have planned. Each day will post something funny, weird or strange … but with some fact behind it. You can then run with it and use it for your own inspirational purposes or just read it and do nothing the choice is yours.
Do you ever wonder what Fluffy or Spot are looking at? You’re standing alone in the room with your cat and he’s looking off to your right like someone or something is standing behind you. You look … no one is there … what does he see?
According to the Mind Unleashed site, on April 10, 2014:
Cats, like some other animals, have the ability to see psychedelic stripes on flowers or fancy patterns on the wings of birds, which are invisible to human vision.
The secret behind the super vision of our four-legged friends is the UV light. According to a recent study cats, as well as dogs and other animals, can perceive this type of light which humans can’t.
“There are plenty of things that reflect UV radiation, which some sensitive animals are able to see, while we are not,”said Ronald Douglas, professor of biology of the City University of London and co-author of the study. “For example, these may be certain patterns on flowers that show where the nectar is, or traces of urine of an animal. Also, reindeer can and see polar bears as the snow reflects UV radiation, while white fur does not.”
Douglas, who specializes in optics, and Glen Jeffery, professor of neuroscience of the University College London, argue that cats, dogs, hedgehogs, rodents, bats, weasels and the okapis can detect significant levels of ultraviolet radiation.
“For decades, we have known that many invertebrates such as bees see ultraviolet light,” continued Douglas, saying that even birds, fish and some reptiles were recently added to the same list.
“However, scientists believed that most mammals cannot see ultraviolet light because they have no visual pigment with maximum sensitivity to ultraviolet light, but instead have lenses like those of humans, preventing ultraviolet light from penetrating into the retina,” he said.
The professor explained that the visual pigments are those that absorb light and turn it into electrical activity, which, in turn, is transmitted through nerve cells. It seems that it is not always necessary for sensitivity to ultraviolet radiation. Instead, transparent parts of the eye such as the cornea and the crystalline lens in some animals transmit wavelengths of ultraviolet light.
This ability allows more light to pass to the retina, “something that would be very useful for a nocturnal cat“, he continued.
Some people, for example, those who have undergone cataract surgery, also can see some of the UV light, but most cannot.
“We all know that ultraviolet radiation can be harmful,” said Jeffery in Discovery News. “I work a lot in the Arctic, where the UV radiation levels are too high as there is much snow and ice. The surfaces reflect 90% of UV radiation, with the result that animals are exposed to it. If you do not wear goggles, your eyes will hurt within the first 15 minutes.”
However, studies on reindeer have shown that repeated exposure to ultraviolet light does not bother them at all.
It is possible that cats, deer and some other animals that can detect UV rays have a protective mechanism. Also, scientists believe that UV light tends to create more blur.
“Humans are good at one thing: they can see more details,” added Douglas and concluded: “Maybe that’s why we have a lens that ‘blocks’ ultraviolet light. If you do not have it, the world might appear more blurred.”
Food for thought:
Story ideas …
What if you could transform or shape shift into a cat or dog form? A magical curse?
Glasses made to see ultraviolet light to fight an enemy on a distant planet?
Maybe ghost communicate with your pets to get to you?
