Greetings All. Just though I would let everyone know my experiences with the Super Pet cages. I planned on getting two kits, so I purchased the 4 story deluxe kit from The Pet Warehouse (WWW.Petwhse.com) for $100.00. This came with the non-funnel version of the 4 story cage, and all the extras. The litter pan (corner style) and playhouse sucked, but the other stuff is sill in use today. The cage was great, as Super Pet has moved away from the wire ramps and shelves to solid plastic. A couple of minor problems with the cage. The tubes that came with the cage to be used in one of the shelves wouldn't fit. I called Super Pet, and they sent me the correct funnels at no charge. Second, my guys quickly figured out how to open the main cage door by grabbing an upper bar with their teeth, pulling back, all while pressing against the door. A couple of clips like for dog chains remedied that real quick. All in all the cage is a breeze to clean and well constructed. This cage worked fine for about 6 months. We could feel ferret math taking hold and were deciding to adopt a 3rd ferret. I wasn't comfortable putting 3 full grown ferrets in the one cage so I started looking into a larger cage. I checked out the Midwest and Marshall Cages. They were larger, but I didn't like the wire mesh ramps. After a trip to Pet Smart, I noticed the newer Super Pet Funnel cages. The new 5 story cage is essentially two of the smaller 3 story cages stacked. I got an idea... I called Super Pet again and asked if I could stack two of the larger, 4 story cages. They had tested is and said it would work fine. I sent an Email to both the Pet Warehouse and The Ferret Store asking if they had any damaged Super Pet 4 story cages that were missing either the base or top plate that they might want to unload. Joe from the Ferret store was the only one to reply. He had a 4 story funnel cage, that had some broken tubes and a badly broken base that he would sell me at a very large discount. ( I didn't need the base, as this was going to set on top of my current cage) So, I bought it. When it came in, I put it together and saved the extra clips they give you with those things. I had enough unbroken funnels to go from one side to the top of the cage and put a plug in the opening on the other side of the cage. I removed the top from my old cage, set the new cage directly on top of it, and used the extra clips to secure the pieces together. My old cage had special thumb tab clips, so the top would hinge open. I used the same setup for one of the sides on the top section of cage. For $60.00, I doubled the size of my kid's existing cage. Geddy, Chewey and Tully now have a 32" by 20" by 64", 7 story cage with funnel tubes running outside it. Not only do they have room to play, but have space for 2 hammocks, 1 sleep sack, 2 litter boxes, 2 water bottles, a food dish, toys and a couple of t-shirts. And for those who question the funnel cages....yes they do play in the funnels. Since I've done this to their cage, they seem healthier, happier, and have more energy during their playtime outside the cage every evening. If anyone want's more detail on how this was done, or is interested in doing something similar, don't hesitate to drop me an email. Mark [Posted in FML issue 2743]
