If this thing can stand the destruction and rambunctious nature of my Australian Shepherd, I'm fairly certain this thing could withstand nukes being dropped directly on top of it. My dog is a drama queen when he has to be kenneled, even if he goes in on his own. The heavy sighs, the full body drops and puppy eyes through the mesh, the whining and scratching. It's his hidey-hole, but like a cat, he goes in willingly only when he wants to (lol).The 36"" was a bit too short for his gangly legs so we had to resort to the 42"", but there is space enough for him, myself (5'3"", 185lbs), and his 10lb cat brother to all hide and have a surprisingly amount of breathing room.Wish I could do 4.5 stars. It's definitely worth it.
