When we found a spot on Wilbur and the biopsy showed melanoma, we knew we must find a few more pigs in case we were to lose either Wilbur or Penelope.  Good news: in pigs, melanoma can recede - and that is exactly what has happened to Wilbur.  But, now we have more oink-oinks.  We love these Kune Kune pigs.  Absolutely filled with personality!
