Okay... So, I have Benny, a 1 year old male. I have had him for 8 months. I got him a cagemate three weeks ago, because even though I have a mom and baby girl pig (Judy and Liza), they are separated by a divider and I was hoping for Benny to get some Piggie interaction. Spencer is 7 months old. I introduced them two days ago. There was sniffing, chasing, rumblestrutting and all that then things calmed down. I caged them and more rumblestrutting and all that happened again then calmed down. This happens every time after i spot clean their cage. Last night and tonight I have heard quiet a showdown I believe. Middle of the night I can hear rumbling and lots of running. When I jump up and turn on the light, Benny is in a corner chattering his teeth and spencer acts like nothing happened and hidey spots are tipped over, hay everywhere, etc.. So I was wondering, pretty much.... What the heck? I haven't seen any actual wounds, so should I assume its just normal guy pig stuff? I haven't been able to actually SEE what's happening, so it makes me nervous!
