The cat keeps meowing at night and scratches the door

Cats are myopic and can only see objects at a distance of about 6 meters. Any further away will be hazy and blurry. Cats can only see a vague general shape of distant objects, but they are very sensitive to moving objects. As long as the object moves, they will react immediately. Although cats are short-sighted, their sense of hearing and smell make up for this defect, so cats are still very flexible in their movements.
Although cats with poor vision cannot see things clearly and are color blind and cannot distinguish colors, the rod-shaped photoreceptor cells on the retina are exceptionally good and are very sensitive to light. They can also see things clearly under weak light at night. . In addition, cats’ dynamic vision is also great, and they can accurately capture even small things that move quickly. Dynamic vision and light perception allow it to see its prey clearly and catch it at night.
In addition, cats have a big advantage with their big eyes - they have a wide field of vision, and the viewing angle can reach about 220 degrees to 285 degrees. They can also see species activities nearby.
