I just would like to add that we always keep a hand on the piggies whenever they want to place themselfs in our shoulders. ;) We take very good care of them, and they are very spoiled piggies ^^
Two of my girls always climb up on my shoulder, too. I put them down a little onto my stomach and they climb right back up to my shoulder/crook of my neck. So cute! Both of your piggies are adorable
