Can you describe his set up?
What is his weight and what size prey are you feeding? Live of f/t?
If he has decent muscle tone and good body condition, I wouldn't worry about the lack of eating right now. My breeder males have been off feed since October and they've hardly lost any weight.
Does he look thin? Does his spine seem prominent?
If it really comes down to it, try live prey to jump start a feeding response. Live small or weaned rat. Or live adult mouse as a secondary option. Mice are like BP candy.
Edit: Interloc beat me. Lol
