I'm not sure how the empty water bottles are supposed to work?
For starters, who has that many water bottles just sitting around? They don't weigh very much when empty, so what's to stop the doe from just moving them out of her way? And if you make it impossible for the doe to move the water bottles or kindle anywhere other than in her box, doesn't that mean she's going to be basically trapped in the box until you come in and clear away the bottles? That could be a lot of pee and poop in the box, to say nothing of squashed babies.
