<3 pig <3
i kept trying to find turnip cagemates that were her age, which means they were old, and they died really soon after i got them. i gave up and just let her live out the rest of her life alone, giving her extra pets and attention. i'm not sure if she was lonely, but she did seem content.
personally, i think the idea of taking pig out of her environment AND introducing her to new pigs sounds like... a lot. i would keep her at home, myself, but maybe the shelter has better advice.
dead pig probably walked the rainbow bridge at the same time turnip did. that thought is comforting to me. <3
