Silly question I know but Peppa a few times has made a tiny little peeping sound when I've gone out for a few hours. I come home and get her out of her cage and it sounds like such sooky little noise and she is so cuddly. Doesn't happen often but I've noticed it a few times. I went to cover her cage as it's bedtime and she started to make that sound again and wanted to come out of her her cage so of course I got her out and have her a quick cuddle and put her back. She seemed quite happy with that as she went back up to her perch. I don't know how describe it but it's such a soft short little peep. It makes me melt.
