Hi, I want to figure out if there's a way to see if someone already has a pet that I want to trade them so that it's an easier convenience, as well as I would not like to trade someone a pet that they're hoarding as I'd rather give that pet to someone else who'd like it as I feel like it's a little unfair if someone is keeping all of a certain pet for themselves (Sorry if this comes off as rude to people who do hoard, I don't care for it, but I also want that people who also want one would be able to get one one day :)
Thank you very much for your answers!
