Have the product designed from the outset as a sleeping pen or retreat and it is super useful! .. Our male has initially a bit reluctant but responded by adding a few treats was it OK for him and now he's in there voluntarily, his dog bed can be left .. He even our cat has sought shelter from the vacuum cleaner there :-) As a transport box I will not use it, I think the cage provides insufficient for protection. Quality: Stable and well made.
