Ninja Lock - Child Door Lock with space for Cat

thingiverse

I needed a way to make the doors in our apartment inaccessible to our newly crawling baby. But, we have a cat and a dog. Our cat still needs to access the rooms that go to the litter box. So, I extended the bar a little bit to allow for an average house cat to slip through the opening. The good news is that now the dog cannot sneak through to her litter box and get her favorite snack. I hope someone else can find this useful
