One: Safe to re-freeze after 2/3 hours of no takers?
Two: What are your thoughts on feeding until the garter wants to stop?

For example my 08 lady blackneck ate SIX small pinkies one after another before she decided she didnt want anymore She is going to be huge! My 08 lady eastern took 5. Both these snakes two days later took 3

Truthfully most of my snakes want to eat this way except for a few troubled eaters. I usually feed on a schedule but wanted to experiment.
