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.
Fleece beds specially designed for ferrets are a great option as well. Litter box: Ferrets can be litter box trained. Ferrets like to use the bathroom mainly in a corner and on vertical surfaces. Use small cat litter boxes or ferret litter boxes. Pellet or shredded paper based litter is best. Avoid cat litter as it can be an irritant. Toys: Some options include paper bags, PVC piping, ping pong balls, golf balls, small cloth baby toys, and specially designed ferret toys. Never give your Ferret any rubber or latex toys.
