Yes and no, I suppose, depending on your view. I mean, I don't feed them anything that's unhealthy for them, but I share my own fruit and raw vegetables with them. For example, when I have a slice of melon, I'll cut off a couple of pieces for my piggies too.

So yeah, nothing out of the ordinary, but if my pigs notice me eating something that they can have, they'll pester me until I give them a piece. XD
