[Thamnophis]

Some 20/25 years agoo we (Reptile zoo Iguana) got piglets from a farmer.The mother of the piglets layed on them. We gave them at our larges pythons and, cut in pieces, at our monitors. Nowadays this is forbidden (giving away piglets when they are dead) to prevent diseases.Another farmer brought us some freshly killed, newborn cats.We tried to feed these also to the pythons, but they would not eat them. When they smelled them they fled. Smell of a predator, I presume.
