I can understand the reluctance to try live. Dealing with and/or disposing of a refused live rat can be a pain in the tush. If you can make a little CO2 chamber though, maybe you could try offering live, and if she refuses it, you can put it to sleep (kill it), freeze it and save it for a later feeding for those that do eat f/t.
Can you get your hands on some frozen mice? Maybe try that. My big girl went off her food around that size and it took switching from rats to mice to get her to eat again.
GORGEOUS lesser, by the way!!![]()
