Answer:
There once was a cat named Pat
Who was known for being quite fat
He loved to play and have some fun
But he always seemed to come undone
One day as he chased a mouse
He tripped and fell in the house
He knocked over a vase, a lamp, and a chair
But he didn't seem to have a care
He just got up and kept on going
His owners' screams he kept ignoring
Until finally, they couldn't take it anymore
And they had to lock Pat out the door
But Pat just sat and licked his paw
He didn't mind being locked out at all
For he knew that eventually, he'd be let back in
And he could cause more chaos and grin.
