hi wicca. my young boy once escaped at 12 months old and i tossed my entire room and entire house looking for him but with no luck. the trick that did work was by starting small and going large if needs be. on the first night i noticed him missing i started with my room...i gutted two pinkie rats, placed one in the open enclosure and one on the floor of my room. i shut my door and turned off all my lights. i checked again 30 mins later and he was there swallowing one of the rats. just play according to their nature...i know that my python hates light so i gave him complete darkness to make him feel more comfortable and it worked wonders. just remember that nothing disappears into thin air, so as cold comfort as it may be, try to relax and feel assured that your jungle will show up. just provide the necessary opportunities to allow your jungle to come out.
btw, i read somewhere that bleeding a rat increases the scent of it so it may be ideal to try that tonight rather then just leaving out a whole mouse
