Today I introduced my new guinea pig (Steve) to my 2 year old pig (Ollie). They've been quarantined away from each other for almost a month because Steve was treated for a resp. infection. Anyway, I introduced them on nuetral territory on my kitchen floor on a sheet. For a few minutes they just ignored each other, but then they finally took an interest in each other. Steve dove under Ollie and Ollie started humping Steve's head immediately. Haha. It was all downhill from there. The next fifteen minutes or so involved them humping each other and following each other around. They shared a carrot and Ollie seemed to be cleaning Steve. I didn't see any biting and neither of them seemed in pain or scared. I wasn't prepared for all the humping, though! Is that normal? Are my male guinea pigs perverts? I think Ollie even ejaculated a couple of times because there were spots all over the sheet, and it wasn't urine or blood. Is this normal? I think I'm shocked. Haha. Its pretty funny actually...I just want to make sure this is normal...and that it will subside.
So, should I keep them in seperate cages but near each other for a week or so before putting them together in one cage? Does it really matter at this point?
