A while back my wife and I adopted a new kitten. Needless to say..Kittens are very curious...and with this curiosity came a cat jumping over the door and into the layout.
So...thinking cap on..I developed a securement method that would keep the cats out. On the left is lexan sheet (going from the staging yard to the ceiling). This will allow a signature piece of the layout to still be viewable. The other solid pieces can be removed during ops...as they are hung from eye hooks on the side of the layout.
