Left Sided Cats

All our 7 cats wash one side of their faces.
They forget the right side and other places.
So they are one sided cats I say;
Filthy cats all night and all day.
Our big Maine Coon can was ALL his face.
A lick of his paw then apply to face at his pace.
His fur is all tangled underneath
He carries a paint brush in his teeth.
It's in the middle of his mouth I see.
To be an artist is what he's meant to be.
He can pick up a biro pen to show he can write.
He chirrups to his six pals saying I am real bright!
