About a year ago, I started converting 4 hatchlings from live mice to F/T mice and then to F/T rats. I successfully converted them all to F/T mice and 3 of the 4 to rats. Unfortunately, I have one last holdout that wants absolutely nothing to do with rats. About 5 months ago, she actually spent 3-4 hours with a rat pup in her tank that actually took up residence in her hide while she sadly huddled in the corner of her tub...
I have hereby thrown in the towel and have ordered a supply of Jumbo mice just for her! That should keep her growing happily for the foreseeable future. Perhaps we'll try again in 6ish months when her supply runs out...
I have tried every trick in the book, but this is my first Ball Python that I haven't been able to convert. A sad day indeed. =)
