I have had my female ball python since April of 2009. She has been a GREAT feeder from day one. There were a couple of times that she refused to eat due to shed but she has usually eaten even during shed.
I tried to feed (frozen thawed) her two days ago and although she was flicking her tongue she did not show any interest. I put her back in her Reptile Basics 2X3 cage and waited another day. I attempted to feed her the next day and this time she struck and constricted........but it was in really slow motion. Afterwards, she did not eat.
Her health seems great. Normally she has a great feeding response but for whatever reason this is not her week. I have heard that ball pythons will go off feed during the winter but she has never missed a meal until this week. To be concerned or not is the question. I will attempt to feed her again next week and see what she does. My male refused last week but this week he was starvin' to death and he hit the rat quick.
FYI.......she is around 600 grams and has been eating small rats. Although the rat I offered her was slightly larger it was well within her limits of size.
