If you're planning to be on the road for hours at a time, the most comfortable travel cage is a large pet taxi. You can hang a hammock from the vent holes and put a litter box in the bottom at the back. I put paper towels in the litter box rather than litter. It's much more convenient for the more frequent "box scoopings" you'll be doing on the road. All you have to do is pick up the paper and dispose of it in a Ziploc bag. Keeping the water bowls less than half full will lessen water spillage. Be sure you put a lid on food bowls if you're going to leave your car parked in the sun or the smell of warm grease will be rather offensive when you get back in the car! Be sure you secure the pet taxi with a seat belt. If the seat belt won't fit through the handle, use a ratchet strap attached to the seat belt brackets.
