A friend of mine recently received a ball python from a friend of his that seems to be badly malnourished. the back story of the snake that was given to me is that she is estimated to be around 5 years old. she was kept in a rather small enclosure, not sure of type, and was only being fed two small mice at a time once a month. our friend brought her with him when he moved in with us. we have 3 healthy normal balls ranging from 3 to 7 months old and i could tell just by looking at her that she was not healthy. we have had her here for 4 weeks and she has eaten one small rat, just out of hopper stage, the first week. two weeks later she ate another, slightly larger but not too large for her to eat. 3 days after eating the rat she bloated up really big around where the rat was being digested and regurgitated the rat. we decided to move down to a hopper for her next feeding, but refused to eat it. she is used to eating mice, and she eats live, not f/t. maybe she is refusing to eat the rats because she's used to mice? she has deficated and it is being saved to be tested for parasites. (one of the 3 regulars we have was housed with her and he seems to be doing fine with eating and behavior.) she doesn't move around much when brought out of the cage. she just sits there, not much tongue flicking either. temps and humidity are fine. i'm pretty sure i've covered everything. here are some pics of her.

i know this snake should probably see a vet, but i was wondering, if just malnourished, how we can coax her to eat. if she is used to only eating mice, should we only feed once a week and then see if she'll move on to rats? i am very unexperienced with sick snakes, as the three we have are very healthy.
