After Zhou Jing left, Zhang Zian suddenly remembered that he forgot to ask her which aquarium she worked at, because there were several aquariums in and around San Francisco. Which one did she work for?
However, this matter was not urgent. It would not be too late to call her when he decided to go to the aquarium. There was no need to ask now. Don't disturb her class. It was not easy to study while working part-time, especially in San Francisco, a city with ridiculously expensive rents.
If he was lucky, he could ask her if the aquarium she worked for was still recruiting. Even if it was not, he could introduce the situation of other aquariums. After all, she probably stayed in San Francisco for a long time.
Famous asked, "That animal just now, is it called a coyote?"
"Yes." Zhang Zian asked, "You haven't been touched by its teeth or saliva, have you?"
"No." Famous was very sure of this.
"What's the matter with the coyote? Why is there such a beast in San Francisco? "It asked and walked back to the house with Zhang Zian.
"Wait a minute."
Zhang Zian noticed that there was a wet spot on the road and stopped Famous, because Famous might step on this wet spot if it took two more steps.
"Is this … water? Or sweat? " He bent down and looked carefully, but he couldn't see it. Maybe it was Zhou Jing's sweat, maybe it was water dripping from a passing car, or maybe it was the saliva sprayed when a Pomeranian barked … it was possible.
Famous didn't understand what was so surprising about a small pool of wet stains, but Zhang Zian's expression was serious, so it did not dare to take it lightly.
"It's not water or sweat, it seems to be … coyote urine." Its nose had distinguished the nature of the wet stain.
Zhang Zian pondered for a moment and drew an arc to it. "Go around, don't step on it."
"Protect the scene?" Famous wondered. It could only think of such an explanation.
"No." Zhang Zian shook his head. "Some diseases, such as mad cow disease, can be transmitted through urine. That is, even if you step barefoot on the lawn stained with the urine of a sick cow, you can be infected."
"Ah?"
Famous was shocked and even thought it had heard wrong. "Stepping barefoot on the lawn stained with urine can be infected?"
"Theoretically, yes. Of course, the chance of infection is very low, but there's no need to take the risk, right?" He looked around, picked up a branch, and dug some soil to cover the puddle of urine.
Although it sounded inconceivable, it was the truth. It was a special virus that caused the spread of mad cow disease … It was not accurate to say that it was a virus. The correct way to say it was a special protein that humans knew very little about, and urine might contain this special protein.
He didn't want his prediction to come true, but it was better to be safe than sorry. If he really got infected because he stepped on urine, it would be a great injustice.
It was fine for humans to wear shoes. Even if they stepped on the urine of mad cows, it would not be a big problem. However, Famous was barefoot, and so were the other elfins. They had to be careful.
Famous bypassed the pool of urine that was covered with soil, and turned its head to look back with lingering fear.
A man and a dog returned to the bedroom on the second floor. The other elfins gathered curiously by the balcony door to witness what had just happened and heard Zhang Zian's words.
Zhang Zian first recorded Zhou Jing's number in his mobile phone, and then relayed Father Yang's conversation on the plane to the elfins. Richard also made some additional additions about Ghent University.
What he didn't expect was to hear the narrative about the coyote attack on the plane and witness it on his first day in San Francisco.
"Why did the coyote go crazy?" Famous's question was also a question shared by Zhang Zian and other elfins.
Since the beginning of the primitive era, humans have dominated the earth for tens of thousands of years. Not to mention the extinct animals, the existing terrestrial animals will basically instinctively fear humans, or try to live in harmony with humans like cats and dogs. How could a nobody like the coyote dare to take the initiative to attack humans?
The possibility of a collective neuropathy did not exist. The most likely explanation was that they were sick or poisoned, which caused them to be delirious and aggressive.
If they were poisoned, at least it would not be contagious, unless they were eaten by other animals after death, causing the poison to spread, but the range of spread was also very limited.
Zhang Zian was afraid that it was some kind of infectious disease that humans had not yet discovered … or some kind of infectious disease that humans had discovered but did not know that canines could infect.
Famous remembered the scene of the confrontation and described the coyote's demeanor, mainly that its eyes were dim and gray, and its lack of sense of direction.
This reminded Zhang Zian of the dog he saw in the pet clinic. It seemed that its eyes were also white and gray, and this abnormal characteristic was quite rare.
Dogs in China, coyotes in the United States … across the Pacific Ocean, is there any connection between them?
Dogs and coyotes are canines. Many people have a misunderstanding that dogs are dogs and wolves are wolves. In fact, dogs are not a separate species at all, and they are biologically equivalent to wolves.
To define a species, it is required that the offspring of this species are stable and fertile when it reproduces within the species, and that it cannot reproduce with other species and the offspring produced are infertile. In short, it is reproductive isolation.
From this definition, dogs, wolves, and coyotes are all the same species. They can freely mate and reproduce with each other, and their offspring are also fertile.
If a certain infectious disease can be transmitted to wolves, it must also be transmitted to dogs and coyotes, and vice versa.
He tried to sort out his thoughts.
He previously suspected that the American dog food called Leshi caused China's dogs to suffer from strange diseases, which in turn caused the waste recycling station employees who secretly ate dog meat to also suffer from strange diseases. However, he was not sure whether the source of the strange disease was caused by the toxins in the dog food or the bacteria in the dog food. He was also not sure whether it was contagious. If the toxins spread between dog food, dog meat, and people, it would be called transmission, not infection.
However, the test report given by Wei Kang, from the routine inspection, did not find any particularly harmful ingredients in the dog food …
Except for one thing – the meat in the dog food, that is, the source of protein was complex. Large particles came from chicken, duck, fish, and beef, these conventional meats, and the source of the ground meat powder was not detected.
The meat powder was not necessarily meat, or in other words, there was a 99% chance that it was not meat. If it was meat, there was no need to grind it into powder. It was generally ground into powder after bones or animal viscera were dried.
As for what animal it was … he always thought it was a stray cat or a stray dog, a cat or a dog's body that was euthanized from the animal shelter because no one adopted it. Was it actually something else? After all, it was easy to leak this information. Once it was leaked by the animal shelter staff, it was likely to be condemned.
Could it be some kind of wild animal – a wild animal that could be used as both prey for coyotes and as a dog food ingredient?
