Dont worry ! My male BP hasn't eaten in 6 months. I try not to worry. He does it every year. I keep records of his weight, and he's lost about 50g in this time. He still has good body definition. Its good to hear you have the same problem, reasures me !! . Offer what he ate before once a week, when hes hungry he'll eat. I would NOT offer other food items, or live as long as hes eaten F/T or P/K before, this can cause a problem, if he takes live then you might have a job getting him back to PK or FT.
