Willow has not been willing to touch any part of herself against the lexan door. She will pass through it only if it is propped open. I tried will all sorts of yummy treats right before dinner to lure her to touch it but she refuses to touch any part of it!
Nahum, is similar to Willow, only I have a hard time getting him even interested in thinking about the windoor. He has never been a huge fan of spending time on the porch, so his motivation to get out there is slim.
