The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air.
And, just to clarify, the kitty litter in your trunk, to be used for traction, needs to be taken out and spread around your tires. Most cars are front wheel drive, so the extra weight alone in the back ain't gonna do you much good.
There's one way to keep yourself in your kitty's good graces: Clean Mittens' litter box -- regularly. Cats like clean litter boxes, just as you like a clean toilet. It's that simple. You won't be able to get Mittens (or any cat for that matter) to use her box if it doesn't measure up on her cleanliness meter.
