I found him yesterday! Rather he found me! After almost four days and fairly cold nights, "misplaced" NOT lost, as I told my husband!, in the house, k2 came strolling up like it was nothing! A bit dehydrated, dark & hungry.. but otherwise not a mark on him! What a relief! After systematic morning and night searches we still can't imagine where he could have been!! Kinda tripping us out! Regardless, after a shower, tummy full of crickets, roaches & butter worms, basking time in his favorite back yard bamboo, hes back home.. tucked away for sleepy time.. content.. FOR NOW! Thank you very much for all the suggestions!
