Glad to hear he got all his skin off! lol

As for feeding, I would recommend going out and getting a food scale with a 8,000gram capacity and a tare function to measure your snakes weight.
The weight of a snake is pretty important to keep track of and can help you judge the size of their meals. I feed 10-15% of their body weight. If that means more than one mouse, then so be it.
I buy bulk f/t mice so I would rather feed multiples then rats.
