I also have female ball python. She has eaten F/T the whole time she has been with me (she is over 2 now and I have her for over about 1 3/4 years).

On several occasions, she has gone weeks without eating, and when she hit about 900 grams, wouldn't eat for several months. It was kind of an adolescent thing I guess.

She went from about 920 Grams to about 880 grams over 3 months and was still happy and healthy.

A lot of people say go to live, and that might entice them to eat faster, but then you might have trouble getting her back on frozen.

My advice is to get a scale, as recommended, and monitor her weight. They can go a while without eating and can use very little energy. As long as she doesn't look too thin, and is not losing substantial weight, I would wait it out.

Don't overstress her by offering food too much. Just keep offering every 7-10 days (or whatever your schedule was) and she will eventually take (I assume).

I have a corn snake and a ball python. The main difference is I dictate when the corn eats (he eats whenever I offer food) and the ball python dictates when she eats. She eats when she wants. Since the fast, she has been eating pretty regularly and has gone from about 880 grams to almost 1100 grams in a several months.

Bottom line: Don't sweat it too much, but get a scale so you can sleep easy.
