Query: Pre-drilled Screw Holes Were Too Big for the Provided Screws

My sister tried to put this together while I was at work. Unfortunately, instead of stopping when she discovered the screw holes were too big she tried to improvise with duct tape and super glue. About 10 minutes after she got it up the kittens jumped on it and the whole shebang came crashing down. If she had not put it together, I would have returned it, but the broken pieces were our fault. Well, mostly anyway, a wooden bookshelf should really be sturdy enough to not break into pieces when 2 six month old kittens jump up on it. I don't recommend this item at all.
