I personally have only had this ball python for about a month, the guy I got her from said she had been on a hunger strike for a month and a half. I've got her to eat f/t once from forceps but she hasn't wanted to eat these last 2 weeks, put her in a brown paper bag for about 2 hours came back and the rat was gone. Used it in the past flawlessy on others in the past hope it works for you. Let me know interested in how it works for others.
