I have found the answer to the problems with midwest cages. I order custom floor from For Ferrets Only. It was easy to install and only cost 12 dollars + shipping and handling. It is made to the exact size and comes with ladder hole already cut in it. It really makes a big difference the open spaces in the cage are now in use and I don't worry about my kids falling and getting hurt. It also makes it easier to hang hammocks and sleep sacks. Best of all the ferrets love it. I put the second floor at the bottom of the top door and the two half shelves that came with it together half way between the 2nd floor and the bottom with a ladder from the bottom floor to the half shelves then one from the half shelves to the 2nd floor. A sleep sack hangs from the second floor in front of the half shelves and a privacy house hangs from the top of the cage just above the 2nd floor. I also got custom acrylic litter boxes from them that fit right into the cage and cannot be moved around. I put one box on each floor with food and water also on each floor. It really makes a nice house for them. I have six ferrets in this cage and they have plenty of room and lots of sleeping space. I also hung some toys and feathers from each floor for them to play with. They also sell a complete line of ferret products. The best way to contact For Ferrets Only is by fax.
