I have a full-grown male BP (approx 4 ft long) who hasn't eaten since September 3rd of last year. I bought him January of last year, I think a breeder had him and maybe he quit breeding? Who knows. But he used to eat a medium to large rat every 2 weeks throughout the summer, then he started tapering off.
He's in a 40 gallon long tank, has a sufficient hiding spot, plenty of fresh water, it stays approx. 90 degrees F on the warm side, with about 55% humidity. He still defecates about once a week, which to me, is amazing. Not much these days but maybe like 2 pebbles worth?
Is this normal?? I don't want him to die, he's been a great pet.
