Hello, I am going to get a hedgehog in november (at the earliest), so I have plenty of time to consider the design for my cage. I recently got two sterilite bins with dementions of 34 x 18" and at one foot tall. That is about 9 sq. feet combined. They come with two lids and have latches attached to the bins. I have the type of duct tubing that many use for their hedgehogs, hoping it will not take up as much room as a ramp would. I have to make it a twostory house because of the limited space. If anybody has any suggestions, please feel free to tell me. I need to attach the top and bottom while being able to take them apart. Thank you!
