when I travel with birds in the vehicle...a.k.a. the momma mobile we put down one of those cheap plastic type table cloths that has the faric backing so not the super cheap but the fairly cheap...what we found is the super cheap slide around and don't get the job done butt he kind with the fabric grips the carpet and so doesn't move. Get one big enough that will go up the sides thaw way any liquids will stay in and not run off and you can just pull it out shake and spray with a hose....dry and fold and you are good to go! I keep them in the vehicles...I have way too many ways to haul birds....show boxes with individual compartments, pet carriers of various sizes, wire cages of various forms from designed for rabbits to yup I can get a turkey in there to....
