Here are the measurements of the cage I mentioned in the other post. The three floors on the inside measure 20x36 Outside measurements are: It's 37.5 inches wide 27 inches deep 56 inches tall (from the bottom of the drawer to the top The front has two full length doors. There are two slide/bolt type latches on the inside of the left hand door. This side can be locked into place so that only the right side can open, or it can be unlatched for easy cleaning. Then on the outside there are two spring/hook latches that connect the two doors. The ramps were too slick and steep for them to get up originally so they are covered with the black stair grip material. We've never had any problem with it and it seems to work great, but if you don't like it I'm sure it can be changed to something different... Email me if youd like some pictures. It might take me a few days to get them since i"m working 13 hour night shifts every night this week until Monday, but I'll try to get them to you ASAP. Thanks! Melissa [Posted in FML issue 4324]
