My sister thinks it ok to buy from petstores. Can you please explain why it is not ok?
I'm not good at explaining anything.

Tell her the mom pigs that have the babies are usually not treated nicely at all, and die very early on, often delivering the babies. Also that there are already too many homeless pigs around, so in buying a pig, you are not helping that problem, but making it worse because it encourages the breeding of more.

X- look around for threads about petstores in this forum section (kitchen). You will find many threads in there about why it's bad to buy in petstores.
