Sleep is for cats

Sleep is for cats
The meaning
Of which
I know not
But yes
To be able
To curl up on the edge of the couch
Or on the top shelf
Under a bed
Somewhere
Where my thoughts
 Can not find me
Would be a grand thing
Crazy it might be
Another thing
Would be great
To play
With my food
Before I eat
Which
Would be done
First though
A nap
In the sun
In the window sill
Yes
I suppose
Sleep is for cats
And
I Know not
What it means
