So Im building marleys cage and i dont fully trust that she will never pee outside her litter box again and so i was going to put a strip of linuleum along the walls of her cage to protect the underneath carpet and then use cauling to seal it. Has anyone else done this before? Do you think it would be a good and safe idea?

I used caulk on my bunny's condo. I didn't really think of them eating it. and they haven't so far. One tip I have is to put untreated wood trim around any openings in the floor ( like an opening for them to jump onto the next level) because my buns ate a whole bunch of the linoleum.
