Midwest has recently upgraded their shelves and ramps for Ferret Nation. I have been communicating with Angie McDonald from Midwest Homes for Pets inquiring about the upgrades that have been made. Unfortunately, the way the shelves attach to the cage has not changed because they hadn't heard from people experiencing the problem of larger ferrets pushing up on the shelves from underneath and causing them to fall down. So, if anyone has encountered this problem please contact her to express your concerns. The company seems willing to change their product to create a better/safer habitat that we will be happy with- I offered several suggestions and explained some of my cage modifications and she was very receptive. This is her email: [log in to unmask] The following link should take you to a flyer which shows the new shelves/ramps and includes purchase information. <http://pics.livejournal.com/dcwriting/pic/0001qpsk> Hope this helps!
