My female rat snake is about 2 ft long and she ran off a week ago when she managed to open up her feed dish after her meal. She then proceeded to head off on a week long adventure. Now she is currently in my printer. She has hidden deep inside the back of the printer. So today I got a live pinky to scent a trail from the printer to a small hide box to try to tempt her out from there. Yours is most defiantly in the couch, I just thought I'd share my story.
