I think I need to clarify my earlier statement about feeding her. I would feed him a medium/large prey item about every 6-8 days for a few weeks, so he can get his strength up, then I would switch to a slightly longer rotation (perhaps 8-10 days). I would still feed a smaller prey item a bit more often, rather than a larger prey item a bit less often, as it might prevent him from becoming overly hungry and a bit too eager to feed. However, this is all just stuff I've read from caresheets. I'm in no way an expert.
