Since you already have one, and are familiar with the routine of caring for a piggie, I vote for a piggie pair!! They too are very sociable critters that needs attention and friendship. They often do recommend getting a pair if you don't have too much time to spend with him/her. Since you do seem limited in the time dept., I think your piggie would love a friend. I have one and am thinking of getting him a pal to keep him company in my absence. Good luck!
