Kij is once again pretty spot on.
I put it a little differently.
You can hope for 'cat resistant'....probably not more. Cat proof? Nearly impossible once they get there single cell brain on a subject.
IF you make an 'issue' of something with violence or spanking the cat, it'll take that as a challange. You are than done-for.
Try water / amonia in a squirt bottle or perhaps a heavy citrus smell which cats do not like.
My cats NEVER looked twice at my nice, tall, Magnepans.....But they DID like music.
Socialize the cat to the room with you there. lock the door when you leave. keep an eye on 'em at all times as you build confidence.
