Nothing wrong with feeding live, but if you don't breed your own feeders, it would probably be easier for you to make the switch to f/t. Having to go out and buy a live feeder each time must be a pain, I buy bags of 25 frozen rats at a time, so feeding is really easy. That would be my major reason for making the switch, and also I have kids that wouldn't much like me feeding live lol. I would think their smallest mouse once a week might be a little small for her though, how big is she? My pewter girl was hatched Aug. 6 (got her in Sept) and she is over 600g and eating small rats (~70g).
