All placental mammals, which include pigs, are connected to the placenta by an umbilicus and therefore they have a scar where the umbilicus was connected - a belly button. In most placental mammals, the scar is covered by fur or hair and is not often seen.
Two other types of mammals - marsupials and monotremes -do not have placentas and so do not have belly buttons. Pigs and humans have them, kangaroos and echidnas don't.

they do indeed have belly buttons. if you think they are cut you should see them when they are born it might put you off bacon for life, or untill you smelled it at least

I'm pretty sure they do because they are mammals and they have to get sustenance inside the womb somewhere.

Don't know, and don't fancy rubbing their bellies to find out, cool question.

I imagine so, all animals that are attched to their mothers womb during gestation have one
