i have a 4 foot bp thats about 4 years old, same situation pretty much. i got him off a friend, he was uncared for, dehydrated and all that fun stuff... he hasn't eaten since december. if there's one thing i've been told 1000 times, it's not to worry. adult bp's can go ages without eating, and if the husbandry is correct and there are no parasites (internal OR external), then he'll eat when he's ready.
