How much does the snake weighs?
What is the enclosure size?
What are your EXACT temps, what type of thermometer do you use, and where do you take you readings?
Are those hides tight and I mean snug around the body like a shell on a turtles back?
What was he previously feeding?
How many times have you tried feeding him total and how space apart.
Number 2&3 are part of the reason you failed, other reasons could be husbandry related hence the need for details.1) Feeding in a feeder box. Offered 2 kinds of rats of appropriate size on 2 separate nights.
2) Feeding in his cage where he lives by introducing the rat to the cage near him
3) Feeding in his cage where I introduce him to the cage after I have taken him out of the cage for a moment.
