ok before it degenerates jennapiggy, lots of people on here are passionate about piggies and the whole micro piggy argument is the closest thing to pouring petrol on a bonfire you can do on TAS...
it will cause a row, micro pigs are at best cross breeds of small species ut are often bred from runts etc in the hope of getting small pigs, there is plenty of evidence on the site of just how big some micro's have gotten!!!
as to the yoghurt, no animal produce can be fed to piggies its EU rules someone will be able to quote the details if necessary.
