I am planning on buying my first herp within the next week. I am in the process of setting a 20 gallon up similar to the sticky. I'll be getting it from a serpentarium, and not a pet store. However, here's my question....assuming I offer it a f/t mouse or rat and it chooses not to feed, (whether because it's winter, not acclimated, or simply not hungry). What do you do with the unused feeder? Throw it out and then buy a new one two weeks later to try again? I assume you can't re-freeze and re-thaw.
