[Tom Cat]

Hi, I'm hoping someone can shed some light my delemma, I have a 6' male Columbian Boa that hasnt eaten in two monthes, I also have a 6' female in the same cage that is eating like a horse? Although the male hasnt eaten in a while, its extremley active and is constrantly streched out to full lenghth and roaming all over the cage. I've tried everything to get it too eats, from small rats to its regular food F/T rabbits?

Any assistance or ideas would be greatly appreciated.

Thank You, Tom
