I LOVE this cart. I used it to secure a tree for our African Gray Congo, Benny. He just LOVES being on his tree with all of his toys! We used in in this fashion so that we can roll the entire unit into any room. That was MUCH easier than trying to pick the entire tree up. I am able to put his extra supplies away in the drawers or in the large area on the bottom. They ONLY problem was from the manufacturing side where one of the pre-drilled holes for the metal bar was in the wrong location. I got a drill bit, measured and drilled my own hole and it works fine!
