Failure to feed can be a number of different issues, from winter fasts to husbandry that’s off to underlying medical issues. It’s not something that can 100% be diagnosed through a post. Most of us would probably agree that going off feed isn’t unusual and 8 weeks isn’t that long as long as she’s maintaining good body condition and hasn’t lost much weight. I personally would bump feeding attempts out to every two weeks. For my own snakes, only juveniles (under 1 year) are fed weekly. Usually i switch to every two weeks somewhere between 1-1.5 years of age. I try to keep my snakes a bit leaner for health, rather than packing on weight, slow and steady is my preference. This is also how I handled two of my rescues (bp and Colombian rainbow) even though both were extremely malnourished and under weight. In those cases especially I believe in a slower pace to allow their system to adjust from little/no food to regular smaller meals. The larger the meal, the more energy required to digest.
Currently my bp Artemis has yet to eat for me, 3 year old female purchased 9/2/18. I’m switching her to f/t because I din’t want to risk live rats, which is what her previous owner fed her. That will be a last resort. She still has good body condition and her setup is correct (88-90F hot spot, 80-82F cool side) though humidity has dropped to the 50’s thanks to turning on the house heat. She’d go to the vet if there were any signs of health issues, but there aren’t, so I’m waiting her out.
