猫为什么嗜食鼠和鱼 小语第八册(五年制)有一篇课文《猫》,其中讲到猫的性格。这里介绍一点关于猫嗜食鼠、鱼和舐毛的知识。 猫是鼠的克星,而又特别喜欢吃鱼。为什么猫有这样的天性?科学家发现,鼠体含有合成牛黄酸的能力,而牛黄酸能提高动物夜间的视力。惯于夜间活动的猫偏偏没有自身合成牛黄酸的能力。显然,如果猫长期补充不到牛黄酸,势必得“夜盲”症,所以猫为了摄取牛黄酸,提高夜视力,就一定要捕食老鼠。同样,鱼肉中也含有大量牛黄酸,所以猫也爱吃鱼。
Why do cats addicted to mice and fish in the eighth book (five years) there is a text “cat”, which talked about the cat's character. Here's a little bit about cat food mice, fish and beard hair knowledge. Cat is a rat's nemesis, but especially like to eat fish. Why do cats have this nature? Scientists have found that mice contain the ability to synthesize taurine, which increases night vision in animals. Cats accustomed to nocturnal activities do not have their own ability to synthesize taurine. Obviously, if the cat can not supplement the long-term addition of taurine, the cat will inevitably suffer from “night blindness.” Therefore, in order to ingest the taurine and improve the night vision, the cat must prey on the rats. Similarly, fish also contain large amounts of taurine, so cats love to eat fish.
