What happens when you forget to change the kitty litter

What happens when you forget to change the kitty litter for 3 days ... and have two cats? Then you put new kitty litter in the poo dome? It's a ladies bathroom at halftime at a college football game.


* Although the cats have names - I've given them the jellicle names of Panther & Tiger

We couldn't even get the top on before my girlfriend's cats rushed the box!
