Query: Very sturdy

This is a great cage. After looking at Petsmart, Target and Walmart I decided that this was the best price I was going to find for a cage. Since it was such a good price I was a little worried about the quality, but it is a great product. I sized up for the cage, which I recommend doing for large and gangly dogs. I got my dog from the pound, and could have gotten a size smaller based on his weight, but decided to go ahead and get one size bigger in case he grew, and boy am I glad I did.This is a very study cage that is easy to set up and take down. My 80lb has taken to sleeping on top of the cage, and while I know that this is not advisable, the cage is sturdy and will hold his weight throughout the night (he is not allowed to sleep on it while I'm awake and can kick him off).HIGHLY RECOMMEND.
