This my second one from you. I think I bought the first one in 2022. The first one is still in perfect shape, but I am having two litters at the same time in October. I LOVE the improvement you made in the square hole and panel screw set so that it doesn't turn when you're trying to tighten it. BRILLIANT. It is the safest whelping/puppy enclosure I've found. Sturdy enough to withstand jumping puppies, but with no space for them to get heads or feet caught and potentially injured. Thank you!!
