A cat’s bizarre behaviour may be more than just feline silly. Cats may be seeing things that us humans can’t.
Pay attention to your cat, notice if it keeps returning to a certain spot in the house, or stares at a particular spot for long periods. It is a quite common experience to see your pet looking at something or someone that is apparently not visible to you.
Unlike humans, a study suggests that cats, dogs and other mammals can see in ultraviolet.
Study leader Ron Douglas, a biologist at City University London, in England mentioned to LiveScience, “Nobody ever thought these animals could see in ultraviolet, but in fact, they do”.
Humans are good at seeing detail, because they have a high density of color-sensitive cells, or cones, in their retinas, which produce high-quality images with just a small amount of light. By contrast, nocturnal animals have eyes that let in as much light as possible, including ultraviolet light, though it may not serve any special purpose.
According to Pet MD:
Cats, dogs, and other mammals are thought to see in ultraviolet light. With this in mind it would explain some behaviors of animals.
Seeing the World in Ultraviolet (UV) Light
UV light is the wave length 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.
When a cat rubs against your legs, it’s not only that it’s trying to get some food from you, but it also means that the cat is sharing its magic with you, its astral force. Read more here.
