Lol! We all get a little off track sometimes! I'm sorry for your loss. I hope you fair better this time monk! I was thinking of also using a self closing latch at the bottom for added security but wondered if a spring load hinge would be enough deterrent to predators...
I know this is an old post but this is the same pop door set up that i was planning on going with. I was even looking to put spring loaded hinges on it as well! My question are, did you try the spring hinges? Did they work well and do you remember what kind/brand they were or where you got them...
