I also gave up and am having to keep my 7 month old in a kennel. I'm sure I had the exact same pen you had (with the zippers at the top) and he chewed right through the side. It took him awhile to do this though. The pen was around fifty dollars. Before that we tried baby gates stacked one on top of another...all different kinds of these...(even one that was mesh) but he jumped right over. We tried to keep him in the bathroom but he made such a mess that had to stop. We gave up and now he is in the kennel everytime we have to leave. No, he does not like it, but at least I know he (and my house) are safe.
