On adult mice I would still keep 7-10days you will notice her roaming if hungry and then try the small weener rats if you have them in , there normally about the size of a large mouse anyway, but rats have higher fat content so just start to space it out till you get to next size. You will probably notice a growth spurt when switching to rats, just remember he is. A smaller dwarf boa anyway
I don't think you will have a problem going from mice to rats eaoecwith boas
