ok,so i havent held my snake for about three days,and today i was gonna feed it and i was wondering where it was (so i could put the head of the mouse facing where he would come from) and he wasnt there! so i placed the dead pinkie (which he does eat) on the floor with a heat lamp over it so it would stay warm,i thought i saw it 2 days ago,but i looked again where i thought i saw it and it wasnt there....so i went along with my normal buisness......does anybody know how i can find it? im thinking going out at night with my red night bulb from my leopard geckos cage and go around my room,when he should come out...........god i hope i find him....any one got any tips??????
