Cats May See Things Invisible To Humans
It comes as no surprise to hear that many animals have better vision and see things differently than humans do and in many cases an animal’s vision allows them to see things humans simply cannot. Up until recently, it was believed that animals could not see ultraviolet trays, but recent evidence is changing that.
This new possibility of animals seeing UV rays comes from a recent study done by biologists at City University London, US. The findings of the study showed that cats, dogs, and other animals appear to be able to see in UV light. Humans cannot see UV light, which is the wavelength beyond visible light from red to violet.
According to Pet MD:
“Have you ever felt that your cat or dog can see something you don’t? Well, you may be right, according to a new study. Cats, dogs, and other mammals are thought to see in ultraviolet light, which opens up a whole different world than the one we see, the study explains.
UV light is the wavelength beyond the visible light from red to violet that humans can see. Humans have a lens that blocks UV from reaching the retina. It was previously thought that most mammals have lenses similar to humans.
Scientists studied the lenses of dead mammals, including cats, dogs, monkeys, pandas, hedgehogs, and ferrets. By researching how much light passes through the lens to reach the retina, they concluded that some mammals previously thought not to be able to see UV actually can.”
If UV light can safely pass through these mammals lenses to their retina then they clearly can see a different world than what we humans see. This takes us to the next question, are these animals, in reality, seeing more than what we originally thought? Has your pet ever seemed to be looking at something or someone else, something you yourself could not see? My cats and dogs have and this happens a lot, but what does that mean?
Is it possible that our pets could be seeing “spirits” or forces of some sort that we ourselves do not see? There is a good likelihood that there is more to this. The study was not about testing whether or not animals could see spirits, but it was, however, determined that their biology allow them to see in a different wavelength that humans cannot and, therefore, will see things we are not capable of seeing. In conclusion, animals have a lot more going on in their eyes than previously thought. This might explain why animals seem to be more in tune with some things when we are not.
Numerous studies have been carried with dogs and their keen senses. There is an ongoing debate on the psychic abilities and sensory preceptors of dogs. We will never be able to confirm these, as we cannot communicate with dogs on the level necessary to gain adequate evidence but it is, nonetheless, interesting and worth the thought.
