Characteristics of cat eyes

1. Cat eyes have greater peripheral vision than humans. A cat's field of view is about 185 degrees, and humans can only see about 120 degrees.

2. A cat’s pupils can expand to 90% of the eyeball surface in the dark, and weak light is enough for them to find prey.

3. The ratio of cone cells in cats is 25:1, while that of humans is only 4:1. Therefore, when it is dark, cats become more sensitive than humans.

4. Cats have only two colors in their eyes, blue and green. Therefore, the colors that cats’ eyes can distinguish are actually very limited. The more warm the surrounding objects are, the darker the colors they can discern.

5. Cats are short-sighted, but their sense of hearing and smell make up for this shortcoming.

The shape of cat eyes changes throughout the day

1. In the morning, they are usually date pit-shaped.

2. At noon, as the light increases, the cat’s eyes slowly turn into a line.

3. At night, the light is very weak, and the cat’s eyes will become oval or round in the dark.
