This is Silver, my het. T.s.parientalis - Red Sided Garter Snake. While feeding her I would give her a worm then walk 6 feet to the fridge to get her another worm.
She was very impatient with me and followed me to the fridge. With one worm hanging out of her mouth she eyed the worm in my hand. After half a dozen more worm and she returned to paddock. She a very good girl.
