So far, I only have 3 Ball Pythons, but that number will be going up significantly soon. To be completely honest, trying to keep them all eating frozen/thawed on any sort of regular basis is getting extremely frustrating. My adult Lesser girl went on a 6 + month long hunger strike after having eaten weekly frozen/thawed on a regular basis with no problem. I really wanted to breed her this year, so I finally gave in and started feeding her live. The life expectancy of a live rat in her tub is about 3 - 5 seconds every 7 days! I'm getting ready to start my own rat breeding program very soon and I swear i'm just going to start feeding live to (at least) my female Ball Pythons exclusively. I also have a Mystic girl, who is approaching sexual maturity and she doesn't want anything to do with eating frozen/thawed half of the time, either. My adult male Mojave won't eat for weeks at a time, either. The wasted frozen/thawed rats are getting expensive and i'm just about done trying to keep Ball Pythons eating them regularly...
