Thats good. The fuzzy mice are just so high in fat and haven't developed their bones enough to provide your snake with the calcium it needs as it grows. I know how that is though, I finally got Amber switched over to rats, and that pic above is the first time she ever ate one. Last monday when I fed her, all they had were VERY small rats, probably the best description would be a "hopper rat" (think mouse but in rat form). Amber got that down with ease. Hopefully they'll have some bigger ones next time.
