I have 3 different kinds that I use. I have a plastic one that I use for all my small animals when they need to go to the vets etc, that I paid about 20 dollars for. I have a soft sided one that I use for Tucker in the car when travel long distances, that I paid 40 for and I have a black metal one that I use for Tucker at night, when we go somewhere with out him etc that I paid 60 for at our local feed store. Whatever you buy just make sure that its big enough for them to stand in and comfortably turn around in. good luck!!
