Hi i have been in contact with the only piggy rescue within a 400km radius and thought it was all going perfectly when she told me a nero 4 wasnt big enough for 2 piggies if this is true i know have to not only get another nero 4 for the new babies(which i would have anyway)but she wants me to add large runs onto both cages before she will consider me for adoption it will cost me around $400 aussie dollars to do this is it really nescesary i meen my pigs seem to be thrilled with a nero4,outdoor run and playtime with us :{
