Once again I guess I'm over the top.
I have two crates at home. I have a playpen in the kitchen with food, water, and a piddle pad for when we leave Sadie during the day. It also folds up so we use this one for travel (hotels). I have a wire crate by our bed that has water and a piddle pad for the middle of the night when she either has to go or is thirsty. I have a plastic crate for in the car and I've just gotten a Kwigy-Bo soft bag because we're going to fly with her. Can you guys think of anything else I need?
