Strange Life of a Cat

The white mice in the laboratory, to put it nicely, are generally milder in temperament, and to put it bluntly, they are called group stupidity. I don't know if it is because of inbreeding.

Recently, Zheng Tan often heard these mentioned in the ppt of Papa Jiao's genetics course, so when he saw the cage of mice, Zheng Tan felt that this was really similar to what Papa Jiao said. Fear was seen in the eyes of the mice, and they might even have thought that the breeder had come and was busy begging for food.

Papa Jiao grabbed a small white mouse from the cage and put it on the table, sighed to Zheng: "Look at it, don't let it run around."

Zheng Tan looked at the little white mouse who had no idea that he was about to face doom, and raised a paw to press down on the little white mouse's tail. The little white mouse whose tail was held didn't struggle too much, but just showed a posture of going forward.

Look, this is the difference between wild and domesticated. If the mice outside are held down by their tails, they will either struggle to break free, or bite the other way around.

Papa Jiao put the cage containing the remaining four mice into an empty cardboard box so that they could not see what was going on outside.

"I don't know how your cats catch mice, or how to kill them. I'm just telling you about our common methods."

As he said that, Papa Jiao took the little white mouse from Zheng Tan's paw.

"Let me tell you, in domestic laboratories, the neck-breaking method is basically used. This is also the method of killing mice with the least pain. If the method is neat, it will not feel pain at all, which is also in line with what foreigners say. Speaking of animal welfare..."

Zheng Tan squatted beside him and watched quietly. He knew that Papa Jiao had entered the state of teaching again. Sometimes, after Papa Jiao was preparing to teach PPT at home, he would give a trial lecture first, and the listener was Zheng Tan. Therefore, as soon as Zheng Tan heard Papa Jiao say the four words "I tell you", he knew that he had entered the teaching state again.

"Cut the neck to death. To put it bluntly, it is the dislocation of the cervical spine, which separates the spinal cord from the brainstem. One hand clamps the neck of the mouse with a tool or directly, and the other hand grabs its tail, and pulls it violently with both hands. , that’s enough. This is one of the methods, and we often use the other method, you can try it too, watch..."

While talking, Papa Jiao grasped the tail of the little white mouse with his left hand, moved the thumb and index finger of his right hand to the neck of the little white mouse and pressed down.

Then, there is no more.

Zheng Tan looked at the motionless little white mouse on the table, then looked at Papa Jiao with an expression of "I like you", and tugged at his ears.

"Look, the operation is actually very simple. Even if you haven't caught a mouse before, it doesn't matter. Just practice for a while. I've seen your speed when you beat Ah Huang. It's definitely no problem to catch up with the mouse."

The Ah Huang that Jiao’s father talks about is a yellow tiger-striped cat, and he is also one of the bad friends that Zheng Tan met after becoming a cat. Unlike the “sheriff”, Ah Huang always does some ridiculous things. When Zheng Tan saw it, he wanted to go up and whip it, but Ah Huang didn't appear much recently, and he didn't know why.

Papa Jiao caught another mouse and asked Zheng Tan to try it himself.

Zheng Tan killed the first mouse and pressed it three times before the poor little white mouse died completely.

When killing the second mouse, Zheng Tan used too much force, but at least this mouse died without feeling any pain. Zheng Tan felt more and more thankful that he had become a cat instead of a mouse. If he went one step down the food chain pyramid, he would have to face an extra level of hell.

"It's easy to dislocate the cervical spine. The cervical spine of a mouse is very fragile. It's mainly due to your unskilled technique," Jiao's father instructed aloud, "Don't hesitate to take the shot. It's best to succeed once, otherwise the mouse will be in great pain. , However, pay attention to the fact that the spinal cord and brain are broken, not the head directly. This requires controlling the degree of force. It is necessary to break the cervical spine without pulling the head off. Some of the students I have taught before have problems with force It directly caused the pressure in the mouse's eyeball to be too high, and the eyeball actually broke."

Zheng Tan: "..."

Nima is so scary!

Zheng Tan looked at Papa Jiao's still calm face when he said these words, and suddenly felt a cold light in Papa Jiao's eyes.

Zheng Tan recalled the topic they had with a group of drinking and meat friends when they went to nightclubs. At that time, someone said: "Actually, the most powerful killers are not those who look fierce on the outside, not those who carry big knife tattoos and wear nose rings." The perfect people are not those who look like they are awesome with knives and guns all day long, but those who look nothing abnormal on the outside but can easily reap their lives the next moment without changing their faces."

So some senior experimenters are somewhat similar to the killer's temperament in a certain way.

The experimenter who enters the experimental state is so fucking scary!

Zheng Tan thought about it, perhaps, Associate Professor Jiao is the only person in the world who taught his cat how to kill mice by neck-breaking?

When killing the third and fourth mice, Zheng Tan obviously felt much better. At least these two mice had a decent way to die compared to the previous two.

Of the five mice, Father Jiao killed one as a demonstration, and Zheng Tan killed the other four.

After cleaning up the five dead mice, Papa Jiao turned around and went to the back room, and soon came out with a bigger cage. There were still five white mice inside, but they were much bigger.

"This is a rat. The white rat used in the laboratory is an albino mutant of Rattus norvegicus. The method just now is still used, but the strength is a little stronger, or a little bit. Find out the essentials, control the strength, and succeed in one blow. I need to do it." Demonstration?"

Zheng Tan shook his head.

"Good boy."

Zheng Tan: "..."

As Dad Jiao said, the rats are a little bit more difficult, but after five rats have tried it, Zheng Tan is also proficient.

"Do you still want to practice?" Papa Jiao asked.

Zheng Tan shook his head.

"Very well, let's stop here for killing mice, let me tell you..."

Zheng Tan tugged at his ears: "..." Here it comes again.

Although the mice have been killed, Dad Jiao's teaching status has obviously not completely quit.

"In our laboratory, in addition to the cervical dislocation method commonly used to kill rats, there are other methods such as decapitation, bloodletting, beating, anesthesia, and poison gas. , a needle is enough, um... next week I will take the zoology anatomy class to dissect a bullfrog, and then I will bring one back to show you a demonstration. Oh, and you have to pay special attention, the laboratory kills cats and dogs, etc. Most of them are killed by air embolism." After a pause, Papa Jiao looked at Zheng and sighed, "Do you understand this?"

Zheng Tan shook his head, his muscles were a little stiff, the hair on his back and tail were still fluffing, and he always felt that the surrounding temperature was so low.

"In layman's terms, this method is to inject air into the vein."

Zheng Tan shivered. I understand this, even if his knowledge in this area is not strong, he knows what will happen if he pumps air into his veins.

"Air enters the blood circulation to the lungs, blocking the pulmonary artery and causing severe shock or death. For example, when you swim from deep water to a diving place, the pressure change causes the air in the lungs to expand, which in turn causes the lungs to over-inflate. If If you don't get rid of the excess gas, or don't get rid of the gas at all, it's quite dangerous, and some passengers who fell into the water on the Titanic died that way."

Dad Jiao suddenly thought that it would be useless to say the Titanic to a cat, so he returned to the topic and made a summary, "So, you must pay attention to yourself in the future, stay away from dangerous objects, and pay attention to self-help."

After practicing the technique of killing mice, the goal tonight was achieved, and Zheng Tan also had a plan in his heart. Although he is helpless about catching mice, since he is a cat now, only cats that catch mice can be recognized, and even that bastard Ah Huang can be caught. Zheng Tan believes that he can do it too.

When he returned to the Dong family compound, Zheng Tan saw a car parked in the open space, and a familiar face with a military plate on it.

That being said, the fat guy also came back after leaving his relatives.

While Father Jiao was going to park in the parking shed, Zheng Tan jumped onto the balcony on the first floor and took a look inside.

There was a bag of instant noodles on the desk by the window, and a fat raccoon cat squatted on the instant noodles.
