We've had our pied since November and he's very stubborn; tried frozen numerous times with no luck. Today I tried a pre-killed small rat (killed it then immediately offered it to him). Nope, he wasn't having any of that either.....grrrrr!! I want to get him over to f/t rats; there's only once store around who has live feeders so I have to make a special trip just for him.
Sounds like your your snake is doing great and settling in nicely.
