Well people here is the instructions my brother gave me an hour ago you take a fert cage and on top remove the wire. next you cut a hole in the wall you want the playpen to be up against. Next get a tube to fit the hole in the wall. Next dig a hole in the ground the shape of the cage laid on whatever side you lay it on about 6 to 7 inches deep. Put stuff like another tunnel and a plastic container for lack of a better term and cover it with dirt for a burrow and then attach it firmly to the side of the house with the tunnel inside the playpen my suggestion use graber screws in every square of the cage to attach it to the wall you want it attached to. Your Fuzzy Babies will love you forever. On a side note my little girl shadow one day when my brothe had to leave the back door open he saw shadow looking out and you'll never guess what she did to come out and visit uncle Joe. She went into the playpen!!! With escaping and being outside for 3 almost 4 days with little or no food and water she's paranoid about the outside without Joe or me and at that she doesn't like it alot. Snickers don't even try to take him outside he'll rip your face off but he doesn't mind the front porch if you leave the door open so he can run in at the slightest noise. Shadow even sleeps in that burrow Joe made for her and Snickers has done that sometimes. P.S. I'll have a picture of the playpen ready in the morning. [Posted in FML issue 4212]
