our Pet gecko is missing, please help

Our pet is missing, but we know he will be crawling around in the dark.
How did he manage to sneak into our house in the first place?


It is troubling to imagine how our pet will be kissing our utensils, and even milk bottles ! yucks !!

We caught it's uncle last time --> http://sengkangbabies.blogspot.com/2009/08/resident-evil-gecko-ji3-leng2.html
