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.
As long as your automated box can work with other crystal litters, Pretty Litter will work great in an automated self-cleaning litter box. If your cat is larger and you have a larger litter box as a result, then buy an extra bag of Pretty Litter and use just half of that bag along with the first bag.
