Why do some people like sleeping on hard mattresses and others prefer softer ones? And why do humans need matresses and beds at all?
Even dogs and cats seek soft beds. They may not build them, but they smooth out sleeping areas.Humans probably always had comfortable beds. Don't monkeys make their own beds with sticks? I slept on sticks before and it wasn't that bad at all. You have to get the right ones though.
When I was little we had a terrier that had a security blanket that he would drag with him wherever he went. When he was ready to lay down he would put one hind foot on one corner of the blanket and hold the other corner in his mouth, he'd then turn in circles until the corner in his mouth was twisted to a point, lay on the blanket with the blanket point in his mouth and go to sleep sucking on it. He had that blanket until the day he died. We buried him with it.lol My dog builds her bed everynight. She pulls all the covers off me, fluffs them up nicely, then plops down in the middle of it.
I can just picture that.Our golden hides under the bunk beds in my brothers' room, surrounded by a mountain of our socks. Its her den.
