猫咪为什么以肉维生?-揭秘猫咪-BBC

Why Do Cats Need Meat To Survive? - Cats Uncovered - BBC

回到农场 约翰·布拉德肖已让农场主给他的猫一顿少有的美餐
Back at the farm, John Bradshaw has asked the farmer to give his cats a rare treat.
这些猫需要自己来处理一只兔子
A rabbit. They haven’t had to catch themselves.
姜黑首先开始进餐
First to the table is Black and Ginger,
它有两周大的孩子需要喂养
the mother of two week old kittens.
它霸占了整只兔子
She takes control of the rabbit.
它需要大量进食因为它有四个孩子需要养育
With four young kittens to feed, she has the greatest need to eat.
姜黑甚至很轻松地赶走了一只比它大很多的猫
Black and Ginger even fends off a much bigger cat with ease.
热衷于生肉是每位猫家族成员的重要生存本能
This enthusiasim for fresh meat is a key survival instinct for every member of the cat family.
许多动物都吃肉
Because while lots of animals eat meat,
但猫是少数必须吃肉才能生存的哺乳动物
cats are one of only a handful of mammals that must eat it to survive.
首先它们的肠道很短 不…它们的捕猎技能很好
First of all, they’ve got quite short guts, they don’t digest plant protein very well.
同时它们需要一些对人类而言的非必需氨基酸
but also they need some amino acids that we don’t need.
较重要的是一种叫牛磺酸的氨基酸
The key one is one called taurine,
它关乎其身体健康
which is essential for their health.
但猫不行
Now we make as much taurine as we need to in our own bodies, cats can’t do that.
因此他们需要从肉里的动物蛋白获取基本的氨基酸牛磺酸 这只是之一
And so one of the things they need to get from animal portein from meat is that essential amino acid taurine.
和牛氨酸一样
As well as taurine,
猫必须从肉中获取18种营养素
there are 18 another nutrients cats have to get from meat that people,
人类和狗可以从蔬菜中获得
and even dogs can get from vegetables.
尸体里有各种各样的营养素
The carcass will give them all sorts of nutrients.
它们咬碎骨头以获取钙
It will give them calcium from the way they crunching up the bones.
嗯 它也会给它们水
Um, and it will also give them water.
嗯 猫喝很少水是众所周知的
Um, cats, notorious for not drinking very much.
事实上 从进化角度来讲 它们已经从它们所吃的肉中
And in fact, evolutionarily speaking, they would’ve got most of their water
获取了大部分的水 所以它们不怎么喝水
from the flesh they ate and they wouldn’t need to drink at all.
猫的祖先可以靠吃生肉存活
Our cats’ wild ancestors could survive only on fresh meat,
它们的肾脏很强大
they even involved more efficient kidneys
所以它们可以从它们的猎物中获取所有的水
so they could get all the water they needed from the prey they caught.
每只猫都有这种荒野打猎能力
This wild hunting heritage is in every cat.
从大狮子到小家猫
From the largest lion to the smallest moggy.
但是我们的宠物猫处在进化变异的边缘
But our pet cats could be on the verge of an evolutionary change.
直至三四十年前 我们才完全研究透猫所需要的营养素是些什么
It’s only been thirty or fourty years since we fully understood what the cats’ nutritional needs are.
在这之前 为了继续繁殖 它们必须狩猎来保持营养均衡
Before that, they had to gonna hunting in order to get a balance diet to continue to breed.
所以五十或一百年里 谁知道又会发生什么呢?
So in the next fifty or a hunred years, who knows what might happen?
它们可能仅仅因为我们可以为它们提供食物
They might very well change and need to hunt a lot less
而有了良好的变异 也很少捕猎
simply because we are able to provide them a balanced diet.
[音乐]
[music playing]
猫通过打猎与它们的家族成员分享 这种局面很可能会逐渐消失
It’s possible that the hunting drive our cats share with their big cat cousins could fade.
只有一种办法——21世纪与我们人类一起居住
It’s just one way–living with us in our 21st century world
会使猫驯服
could be taming our cats’ wild side.
