How sweet! When we introduced Linney and Sundae, it was sweet how quickly they accepted each other. The sniffed noses and followed each other around. Then Sundae went and sat right next to Linney and they each were trying to get back to one another when we put them into separate cages, so we moved them into the same enclosure earlier than planned. I was SO relieved that it was that easy... I think that Linney in particular was lonely after losing Frenzy a few weeks before (she had never been alone prior to that) and Sundae was very young and is very laid back and was perfectly happy to let Linney be dominant, so it all went very smoothly.
One of my favourite memories is the first time Linney caught site of Sundae (during the quarantine period they were on two different floors of the house and really didn't know the other was there.) I let Linney see her through the bars and she was so excited to see another pig that she popcorned! It really makes you realize that they are social and do thrive on company!
