Our crate had two little water troughs in with funnels for topping up the water without opening the crate. The cats water is topped up at the halfway point (the landing in LA), but they have no food or litter tray, and you are told not to feed them the day of departure (so they have less in em to poo everywhere!). I was really worried about this, but everything was fine! Mogs were hungry on arrival but the crate wasn't that smelly! We lined the bottom of our crate with the stuff you put in dogs beds when the puppies are young (like a sheet of disposable nappy) to help keep it clean and dry.
