Just to be clear, I didn't actually consider force feeding.

I just meant that I'm glad nobody else considered it.
By the way, is it even possible to "starve" a garter into accepting food it has previously refused, or is there a realistic chance that it won't give in?
People have said that it's not uncommon for them to start fasting, especially if they've been over-fed. What kind of energy reserves can they keep, how long do they last?
