Our 3 month old cornsnake escaped around Christmas time and reappeared - alive - yesterday evening. After 7-odd weeks without food he is very thin. Have given him a defrosted pinkie this morning but he is not eating it. He is moving around a little bit in the vivarium, staying on the heat mat generally (temp 26.6C), and drinking water occasionally. I've left the pinkie on the heat mat near him, and drawn the curtains and left him alone. He's been like this for 2-3 hours. Any ideas / suggestions to get him to eat? Thanks.
