I run a teeny tiny micro-rescue called New BeGUINEAings (you can look it up on Facebook, if you have an account there), and I currently have two pregnant piggies in my care. Both Perdita and Winter are most likely due in around a week, and their bellies are kind of all kinds of crazy at the moment. Limbs flailing everywhere!
This is a video of Perdita's belly I filmed today:
My favourite part happens right after the 1:10 mark.
