The beginning of a work about animal eyes.

Everyone has seen cats, right? So who can tell us what's so special about it? No. Then listen to me. Its hearing is particularly good, its smell is better, and its eyes are particularly strange.

Listening: Cats love to sleep during the day. They always squeeze their ears under their forelimbs when they sleep. In this way, they can protect their ears on the one hand and stick them to the ground on the other. As soon as they hear the mouse's movement, they will get up and catch their natural enemy, the mouse.

Smell: I have a cat at home. It is not only good at catching mice, but also good at smelling things. I once did an experiment, blindfolded it first, and then put the fish pieces and vegetables together in front of it. I saw that it ate all the fish pieces and walked away, but the food was still in the bowl. I saw it. I was dumbfounded.

Eyes: My cat's name is Xiao Huanan, because its fur pattern color is the same as that of the South China Tiger in the animal world. The old man said, "There are three changes in the cat's eye." I was curious, so I went to observe it. In the morning, I got up to tease the cat. I see that the cat's pupil is oval. I went to feed the cat at noon and found that its pupil became a vertical line; I can't sleep in the middle of the night. I got up to watch TV, only to find that the cat's pupil became round, like a full moon of fifteen or sixteen. Cat's eyes are really different. I checked the information about cats, and it turns out that the cat's pupil changes only three times under the change of sunlight: under the irradiation of moderate intensity light in the morning and evening, the pupil will form an ellipse; In the strong sunlight, its pupil can shrink very small, like a line; In the case of dim starlight at night, the pupil can be enlarged into a circle. There is also a proverb about the cat's eye changing three times a day: "Yin Mao is as deep as a jujube pit, Tatsumi as a noon line, and ugly as a full moon."

Reading this information makes me refreshed. It seems that knowledge is as boundless as the ocean.

(2) Rabbit eyes

Many people have raised rabbits. Everyone knows that rabbits have red eyes, but one person didn't know and made a joke.

My little aunt lives in Xiaoshan. There is a person in their market who has never seen a rabbit. He heard that rabbits are gentle and lovely, so he bought one. He raised rabbits for the first time and didn't know their habits, so he asked around and learned something about their habits. Once, when he went to feed the rabbit, he accidentally found that the rabbit's eyes were red, which made him break into a cold sweat. He thought the rabbit had pink eye, so he called the vet at once. The vet ran to see the rabbit and said with a smile, "You are such a fool. I made a trip for nothing. Don't you know that rabbits are born with red eyes? " Hearing this, the man suddenly realized.

Hey! What bad luck for people without knowledge!
