Would it be dangerous to make a cat transit system that also goes through the walls, ceilings and floors leading to different rooms?
No, I remember watching shows about people doing it in the 90s on animal planet, just plan it out very well , inspect it every once and a while, and make sure you can get to every part of it in case of freak emergencies or something.

Careful OP. This is a slippery slope to becoming a crazy cat person. I knew a guy who converted his 2.5 attached car garage into a cat house. Ramps, platforms, levels, tunnels, all sorts of crazy shit. There was even a giant screen so the door could be open and the cats could get fresh air. Literally spent thousands of dollars doing this. There was something like 8-10 cats living in there. On top of all that he fed the strays. His wife finally had enough and left him. I cringe at thinking what that house looks like today.
Why are cat people such crazy faggots?
