I have no idea of how old he is I just posted a picture he is 196 grams as of a week ago and about 1 foot 9 in. Also I feed him live hes been on live since we got him in dec and the person befor us had gave him live to we have tried many many times with rats he just wont take them dosent even attept it but we put a mouse in there and within seconds he snags him I always try the rat first and watch him for about 30 mins and no I never take my eye off him also have my trusty stick ready if the rat tries to bite him but no luck so take the rat out drop in the mouse and bingo he takes it right away I have pics on my profile also on my photo bucket profile
