There's a FReeper who has a pet snapping turtle and I mean an actual pet. It roams around her house and comes when she calls it.......I wish I could remember her name.
There was a biography about a remarkable woman named Grace Wiley. She really existed and was a reptile fan. She had pet crocs which knew their own names and came when she called.
She tamed cobras also.

Died of a cobra bite.
