I am relatively new to ball python husbandry (I've been caring for my friend's for about a year now, and finally decided to adopt my own). He is a ~400g male that just turned 1yr old and has been feeding live (currently weaned or rat pups since hatching). I've had him about a week and a half now and he hasn't been taking the f/t weaned rat that I am offering him.

My situation is a little tricky. The only reptile store near me doesn't sell live weaned or pup rats, only frozen. After 2 attempts at feeding him, he completely ignores the frozen food and shows absolutely no interest in it whatsoever. I have tried waiting for him to come out of the hide, handling him before an attempt - to wake him up, dangling the rat in front of him, and leaving him alone with it.

I am concerned with how long it might take him to accept a meal, and am wondering what an acceptable amount of time would be to persist trying to get him switched. I am also looking for any tips you may have for me.
