I have a Carpet python around three years old now, after the winter, she doesn't eat even one, I had tried small rabbit, russian hamster, giant hamster and big rat and of course small rat, she's interested on it, I can see she really want to eat, but finally she went away every time, my room temperate is 86 degrees fahrenheit, with no heat pad and basking spot now, but she still doesn't eat, what's happening to her?
