Cats’ preferences are not just food and toys. If breeders want to take better care of cats, they need to pay more attention to cats and care for them in all aspects, especially pay attention to some life details of cats. For example, what is the cat’s preference for color? What color will it like? As for the analysis of the colors that cats like, we need to start with the cat’s vision. Cats’ vision is naturally very sharp. They can clearly distinguish distant objects when the light is very weak, even at night. Moreover, cats actually prefer a darker environment, and they have a sense of security for this environment. When the light is too strong during the day, the cat’s pupil automatically closes and becomes a fine slit to avoid excessive light intake. However, in the dark environment, its pupil will automatically adjust to a large size to increase the light permeability as much as possible. A cat adjusts its pupils as quickly as the shutter of a camera. This can ensure that in the process of rapid movement, the cat can quickly and accurately adjust its vision and focus according to the intensity of external light and the distance of the object to be seen, so as to see the object clearly. In fact, in our daily life, dogs, like cats, are born with color blindness (or severe color weakness). Cats have poor perception of color and have no special preference for color. However, smell is indeed the most sensitive of cats’ senses. Kittens, in particular, don’t like or hate color. They only have a preference for smell. If the cat wants to see the color of blue, purple, etc. But for brown, red and orange, they can’t be seen. The colors seen by the cat are like black to gray scale. The color saturation that cats can see is low, so the color in their field of vision is not as bright and vibrant as we humans see. It can be said that the most common thing for cats is gray.
