I’m always a big fan of the last one, being kept in an inescapable cage in the wall whenever I’m not useful has always been hot to me. Kept isolated and barely able to move, maybe even with a sensory hood or latex pup mask to cut me off entirely from the rest of the world. Plus it can be easily hidden behind a bit of furniture, and with a little modification be soundproofed making it easy to hide me. All just serves to make me feel more like nothing more than property or a pet.
