i just got 2 female piggies,in 5 days the little one died. i was so devastated to say the least. she didn't seem sick in any way. i think the other one bullied her and didn't let her eat. she seemed dominate since day 3. it all happened so fast. i just had the other one in for a check up at the vet,she's healthy as. i'd like to have two, i think a buddy would be good. what is the best way to introduce a new one? same cage? i am worried this one wants to be an only piggie.
