This is my first BP, she's 10 years old and currently weighs around 1534 grams at her last weigh-in. Her old owner only fed her two large live mice anywhere from every two weeks or every month (at our best guess). She was 1300 grams when I got her and was eating like a pro (took no work at all to switch her from live to f/t mice and then again to rats, and ate consistently every 7-10 days) on top of putting on that weight, but late last month and since then she's been insanely active and refusing to eat.
The only changes to her tub have been a new hide I gave her at middle of last month, but I'm still worried since she's been so active she only seems to stop when she's absolutely exhausted. I'm guessing maybe she's just kinda taking a break from food since in 10 years she's never been fed regularly or this much protein, and it's also the height of winter which is breeding season, right? But since I'm not a breeder and she's still my first owned BP, I'm obviously not 100% and would love to get some opinions/advice. (Also, kudos to me for letting myself read husbandry horror stories and it making me totally paranoid that everything I'm doing is wrong lol.)
