first, make sure your husbandry is within proper range.
once you have that right (if its not already), you can try again tonight, but i would just set the rodent in the enclosure and leave it over night, instead of holding it in front of him, if its not gone by tomorrow, take it out and try again next week. if he refuses a couple more times, you can either mess with the temps of the rodents, or try live.
how are you thawing?
