After losing my last piggie Harry in April, my vet asked me to adopt a boar (Cinnamon) after one of her clients surrendered him. Cinnamon is only 2, so I thought that he could use some company, so I got another little boy - Pumpkin. For the past couple of weeks they have been getting along great. Then, last night, I took them out to clean the cage (3x4) and put them into a smaller cage. After a few minutes, they were in a ball squealing. I snapped my fingers and gave them a firm "hey" and they separated immediately, however Pumpkin had two little nips, one of which was bleeding quite a bit. I put them back in their usual cage but Pumpkin seemed scared and kept running to the opposite side of the cage from Cinnamon. Overnight, I put Pumpkin in the upper level and moved his food & water up there, and he has stayed ever since. He has a ramp to get down, but hasn't. I'm not sure whether to just leave it, or to try to reintroduce them & see what happens. Any suggestions? Was this an isolated incident because they were put into the smaller cage and in unfamiliar territory?
