I found this in a collection of children’s poems by Jan Dean called Wallpapering the Cat:

Cat

My bones are rubber jelly

I leap but never fall

I lie like a long fur collar

On the shoulders of the wall.

My eyes are ancient jewels

Like gems from Pharoah’s tomb

Even when you think I’m sleeping

I monitor the room.

My soul is grey and misty

Shadowy… Secret… Free…

I rise like smoke, escape and go

No one possesses me.
