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.
Many who use non-clumping cat litter find that they need to be replaced the litter and clean the litter box at least once a week. Non-clumping litter is typically made of clay, though there are other types available such as plant-based alternatives (e.g., pine, corn, wheat, beet pulp, and wood). Some people prefer non-clumping litter because it is often less expensive than clumping litter, and others choose it because their cats prefer it.
