hello again, my newly found wild garter has been doing great, he (assumed he) has been eating well and i just had a question.

i have been feeding him every 3-4 days, 1 baby crawler each time (3-4 days meaning if he doesnt seem eager the 3rd day, i offer again on 4th day, and he has yet to refuse on that 4th day). this is my 3rd time feeding him with tweezers and this time right after he got it down, he became way more active in tasting the air, and i was wondering if he wasnt wanting more. he also opened his mouth a few times and it seemed like he was just setting his jaw, but once again, i was just wondering if he may be wanting a bit more to eat, i havnt offered him any more, i figured i would get some opinions on the matter before i did... he is about 10 inches long, and i feed him live crawlers that are anywhere from 3-4 inches long. ive read its pretty hard to overfeed a garter, so my only concern is under feeding him.

thanks
