I know I need to get more toys for them also, please excuse the mess, it's deep cleaning day. As for why all of my girls are single, my younger boar is neutered, my older boar is not (he's 6 or 7 years old and not a candidate for neutering due to chronic respiratory issues) and all of my lady pigs hate other lady pigs and have all drawn blood from each other when I tried introducing them in a large, neutral cage with plenty of food so bar buddies they are/have. Maybe a tad excessive as each girl has a minimum of a 2x5 CnC cage and my boars share a roughly 2x9 CnC cage. (The Midwest cage dividing my girl Sylvie from my boars Guinness and Gatsby has been divided down the middle by two CnC panels and the large cage on the far left of my boars cage is actually the lid to the cage that my girls Judy and badger shared before I rescued them from a neglect situation. I find it makes an excellent travel cage and cage extension without the filthy bottom it used to have)
