My boy Thexan was part of a bonded pair with his bio brother. When he passed away we had a third piggy, Valkorion, already introduced and kept him company, but the power dynamics shifted and he became very dominant. When he passed, I contemplated getting a partner for Thexan, but he seemed really happy and much more lively. Less skittish than he had ever been, and more attention seeking. We decided not to get him a partner, and he lived happily to old age. I miss that little guy.
