We have one of Peter Koch's cages and we LOVE it! Of all the cages that I've seen, his are great. I'm not saying that there aren't other good cages available, just that we like his. I wish all our cages were his. ~Grin~ He custom makes them. They have vinyl coated wire on the full floors and the ramps. Each level is easily accessed and the trays are pull out. They come in different shapes and sizes. I believe he will only make them as large as will fit through a doorway. (In case of a fire, you can take the entire cage out). He lives in New Jersey and he and his wife operate Friends of Ferrets Rescue and Shelter. His phone number (as listed in Modern Ferret) is: 609-586-0007 Tequita and Larry Williamson Ferret Haven The Piedmont Ferret Association "The Miracle of Life is Seen In All Creation" [Posted in FML issue 2592]
