Ok lol I said "it may help some people" but the idea does not have to just apply to bps. any one with a pet that they would at least like to keep contained in a room (if it escapes it's cage) can benefit.
I really do like the idea of the draft guard thingy. Maybe we should promote both of them together : automatic door closer and draft guard and or pet guard ; )
It's one thing to know your snake is loose in a room. It's a whole other feeling when it can be anywhere in the house.
