Author: admin, 22.04.2015Many people think that dogs and cats are completely color blind and can mainly see only in shades of black and white.
But tests by scientists showed that dogs and cats can indeed see colors—just not all the same colors that humans can see. Like dogs and cats, people can also have color blindness, which is also called color vision deficiency. The truth: This is perhaps one of the most widely known and dangerous of all myths regarding cats, because unfortunately many children have tried to prove that it is true. The origin: This myth probably stems from the fact that cats are very supple and resilient animals, even when they are ill or injured. Of course, there is a distinct difference in aging between small dogs and giant breed dogs. The truth: Although cats do see better in semi-darkness than people, they cannot see in total darkness. The origin: This myth originates from people observing their dogs eating grass and then vomiting.
The truth: There actually appear to be two distinct types of grass-eating behavior in domestic dogs. The myth that cats and dogs are fully colorblind has been around for quite some time, despite the fact that it has been proven false for nearly half a century.
One thing cats and dogs both have a lot of, though, are rods in their eyes, which, among other mechanisms they each have, allow them to see much better than humans in low-light situations. Chocolate is poisonous to both cats and dogs, though cats usually aren’t interested in eating chocolate due to lacking the ability to taste sweet things.
Interestingly, a study done in Hungary has recently shown that dogs can judge with remarkable accuracy (about 83%) the size of another dog, solely based on the growl of the dog.
In addition to having difficulties with the color red, cats have a measurably lower cone density in their eyes than humans do, and so will not perceive even the colors that they *CAN* see to be as rich as diverse as humans can perceive them.
Cats do have a *far* higher density of rods than humans, which lends itself perfectly to seeing extremely well in very low light conditions. The case can be made that cats are more intelligent as they have better luck surviving on their own without human care (though they live far longer with human care). I have heard that many cats which have just one blue eye have a deaf ear only on the side of the blue eye. Here are some truths, facts and falsehoods about the top 11 most common myths about dogs and cats. However, they see differently than most people do and are less able to distinguish between colors.
Cats have a keen ability to get out of situations that would probably be the death of lesser animals. It probably comes from simple math: an average life span for dogs is 10 to 12 years, and multiplying this by seven equals 70 to 74 years, roughly the average life span for people today.
Dogs can learn new tricks, skills and commands within their physical capabilities until the day they pass away. It probably comes from the fact that most cats do purr in the presence of their owners when they are being petted, which we interpret as a sign of happiness.
Some dogs graze casually, taking only a few nibbles of grass at a time, while others chow down on grass vigorously and with a purpose. Most cats are better independent hunters than most dogs, fueling the argument that cats are smarter. Scientists use sophisticated tests involving food and colored panels to determine whether animals can sense different colors. Cats are indeed very athletic and agile animals, and they do have a unique instinctive ability to twist themselves around in mid-air to correct their position during a fall. There are many reports of cats surviving for lengthy periods of time in very harsh conditions, even without easily accessible food or water.
Their development in the early years is about the same as other breeds; however, large and giant breed dogs developmentally are much older than smaller breeds in their later years, starting at about 7 years of age. Dogs who wolf down their grass tend to vomit it (and other stomach contents) within a matter of minutes. If a certain color choice gets you fed faster, then it’s a sign of intelligence to learn to pick it, and the animal which can learn this will be more likely to survive than one who refuses to learn out of pique, in many contexts.
Cats are trainable, but dogs are persistently far more trainable to do many more things, which feeds the argument that dogs are more intelligent.
Dogs frequently wag their tails when they are agitated, irritated, tense, anxious, annoyed, frightened, angry or aggressive. The related myth that cats always land on their feet may also contribute to the myth that cats have nine lives. That does have to do with them being more interested in pleasing humans– this is because they are pack animals and follow a leader, cats are not pack animals and do not follow a leader.
As a result, it appears that dogs cannot easily distinguish between yellow, green and red, but they can identify different shades of blue, purple and gray. Interestingly, researchers have found that dogs do not normally wag their tails when they are alone, even if they apparently are happy or are in a pleasant situation. With patience, kindness, persistence and consistency, owners can teach their older dogs all sorts of new tricks, such as sit, bark when the doorbell rings, fetch, lie down, roll over, play dead and shake or “high five.” As long as a dog is bright, alert, responsive and healthy, there is no reason that he cannot keep learning new things throughout his life.
