Their ancient instincts persist. Dogs, for example, often "make their beds"— as humans describe it —by scrabbling on blankets, sheets or doggy beds, then turning a few times before settling down, a habit that probably comes from an age-old instinct to create a safe, warm place to sleep.
它们古老的本能一直存在。以狗为例，它们经常“铺床”——就像人们所描述的那样——在毯子、床单或狗窝里乱挠一通，躺下之前再翻动几次，这个习惯可能来自于一种古老的本能，它们想创造一个安全、温暖的地方来睡觉。
