Thank you to so many people who responded about my questions about ferret playpens! Your information, experience, opinions, and suggestions were a great help. Based on my information gathering, I did go ahead and order a Marshall's playpen from theferretstore.com. I spoke to their customer service, and they assured me that I could return it with no problems for any reason, including the ferrets climbing out of it. I was concerned that if it wasn't defective they wouldn't accept a return...MAN, that store is wonderful! Great customer service; great products, selection, and prices; free shipping; liberal return policies, and they're registered through iGive.com, so a portion of my purchase goes to charity...they even have 2 of Richard Bach's Ferret Chronicles books (I bought both from them, I wish they had the rest!). This is the best store in the world. [This is not a paid testimonial....but Joe, if you're reading this, feel free to send me a check!] Anyway, if the playpen works out, I will order the expansion pack(s) and make it bigger. If it doesn't, a couple of people told me that they put PVC pipe on the top to make it impossible for the ferret paws to get a grip on it to haul themselves over. Several people told me to use cable ties to secure the panels, and someone sent me photos of how she used cable ties to attach the PVC pipe to the top. So tomorrow I'll pick up some cable ties, and then sit out on the curb anxiously waiting for the UPS guy. (Just kidding about sitting on the curb). I'm really excited about this, and I really feel it will enrich my ferrets' lives immensely. Thanks to everyone who took the time to write, it was really helpful! Chana and the soon to be less-cooped-up 4. [Posted in FML issue 4289]
