My duck toller is very clever and is obsessed with food. Every garbage can we had, he some how figured out how to get into it. We kept getting bigger and bigger cans but he still figured it out. It got to a point where I had to figure something out. I found these plans online and began to plan it based on the measurements I needed. I made a lot of errors because I am in no way a carpenter but this may be my best piece. It’s so easy to use and helps make our life easier every day. And best of all, it’s toller proof!
