In real life, lions basically sleep, eat and have no props.

There a lion sleeps beneath a shrub, on the leafless twigs of which mice are at play.

Did you think the lion was sleeping because he didn't roar?

But we drove slowly past the tree beneath which we knew lions were sleeping.

So the boy and the lion slept soundly side by side, till the sun rose.

In a den of hungry lions, the lions slept beside him, etc.

IN the jungle, the mighty jungle, the lion sleeps tonight.

In a den of hungry lions, it is said the lions slept beside him.

At times the boy was restless, wandering through hill and jungle by day as the lion slept.

On a night, when all the lions are sleeping, they awaken to hear a gunshot.
