Drawer lock

We have a small cat - it's a three year tomcat from the animal shelter near. He's cute but has bad habits. He always in the night opens all drawer in kitchen to inspect the whole room every centimeter he can get to. He has a lot of toys, we play with him every day, he is not alone and has a companion.

But to prevent him to get always to the trash can to get everything out of it, i designed a simple lock for the drawers. It must not be screwed or glued. It simply connect the lowest drawer with the one above so he need more force to open them. This worked for us great.
Sorry Knopfi ;-)

I designed this using Fusion 360 hobbyist license.
