When I bought my cage a couple months ago, I purchased it at a farm store (called Central Tractor). The cage I bought was 24x24x16 and it cost me $16.00 (yes sixteen dollars!). They had larger ones that were 30x30x24 or something, I just cannot remember now, and those cost $25.00. (note: these cages do not come with the drop-pan, that needs to be purchased seperately) The only catch is that you have to assemble these cages yourself, all you need is a pair of pliers, because they includes the "clips" and all the cage walls/door, etc... There is a certain type of pliers that are made specifically for fastening those little "clips" around the wires of the cage to keep the sides together. But i just used regular pliers. It did take a couple hours to get the cage completely assembled because the pliers were strange to work with at first, and because you have to fasten the "clips" every 2 inches or so. But now I have a very sturdy cage that seems to do the job just as well as a pre-assembled one. My ferret is loose all day so there is no question of him being in a too small cage. And I only put him in his cage when I go to bed, and he is good enough to sleep through the entire night with no problems. Hope this helps!! Aprille [P.S.] I forgot to mention that It would be very easy to stack these cages up or assemble them any way you like, inorder to have a much larger cage with 2-3 (or more) levels.
