I just got a new pair of ball pythons. I believe they are both 07's. The male spider is around 500+ grams and the female is around 300+ grams. The guy who I bought them from wasnt the original owner but he knew they were on a live rat diet. Now I have had them about 2 weeks and have fed twice. I offered them ft mice. The female at first was striking defensively, but eventually wrapped up and ate the mouse both times. Now the male is not interested in the ft mice at all. How do I get him to convert to ft mice from live rats?
