Wow that is crazy! And completely understandable as to why you are so mad! I must be lucky because of all the cats I have had, none of them ever cared about the dryer. Well when I opened it up and their are warm clothes in it they would try to jump in, but they never cared about going behind it or beside it.

I hope you will find a great solution so that you don't have to fear for your kitty or your dryer anymore.
