I am keeping my sisters ball python for her for a bit. The snake is just over 5 years and has always eaten frozen mice. My sister hasn't been able to get her to eat frozen mice in almost 2 months (she trides feeding the same way she always has), but to no avail. I got her snake yesterday and tried feeding the snake a live mouse, figured if the snake didn't eat it I could feed it to my ball python. She grabbed the mouse aND downed it in less than 10 minutes. Any ideas why the snake wold become so disinterested in frozen after all these years?
