I got my piggies harley and squeekers over christmas, and they were settling in fine. They were becoming easy to cuddle and becoming right at home. They had a little tiff as girls do. However i noticed the past couple of days there behaviour has changed. They seem to be jumping alot and running around like mad. Also making a lot of noise. Harley who was the most comfortable being held has become really unsettled and doesnt seem to enjoy it anymore. I have noticed harley seems to squeel the cage down when i cuddle squeekers. Whats this all about and should i be worried.
