Hello,
I am in the process of building an enclosure for our cats adjacent to the garage. I want to install a cat flap in the wall so they can get in and out of the garage, where I have built a small room for them. However, I'm a bit unsure about what I need to consider before cutting into the wall. It's a newly built garage with wood paneling, so there is plastic, etc.; how should one go about making everything tight? Does anyone have experience with something similar?
