The Cat On The Wall

The cat is on the wall
 knows  not how to jump
 which side of the wall
 would hold a trump
 it looks this way and that
weighs the pros and cons
 poor me, it is only a cat
it sits there till dawn
knows not this side or that
cries with a meow mild
 poor me, it is only a cat
to the left it tries to slide
checks itself in a way
tries  the other side of the wall
 no, nay it sits all through the day
 so came the idiom in call
 the cat on the wall.
