I've had my BP for about a year and things have gone well. The PO fed him live mice once a week and I moved him to F/T mice and then rats, and he has eaten well, weekly, for the past 10 months or so. He's also grown a lot and would shed monthly. He has been quick to grab them the f/t and get them down. But starting about 2 months ago he stopped grabbing them so I'd lay them in his cage and he'd eventually eat them. He stopped eating a month ago. I'll now dangle the F/T rat and he'll just move away, instead of hitting it like he used to do. The past 4 weeks I've been removing the f/t rat after leaving it in the cage for an hour while hoping he'll eat it. Should I be worried? Do BPs go on a fast? And for how long? He seems to be healthy. Nothing has changed in his environment.
