I haven't posted on this site yet, but thought I would reply to Lisa's post on opening cages. I have a two+ year old male ferret (spaz) who opens his own cage. I have to tie it shut at night so he doesn't get stepped on. A boss of my husband's found Spaz in the woods and we took him in (about 1 1/2 years ago). He was never claimed through our paper ad and I am very happy he wasn't. He is a great ferret. So, who knows what he went through in the woods, but yes cage opening is possible-even when the latch looks/feels sturdy. Karen [Posted in FML issue 3475]
