Remember if you do do(heh I said doo doo) whole prey that variety is key. Just mouse diet is no better for Otis than any other unbalanced diet. Toss in some other mammals and lizards and birds. Bugs can be a fun treat too.
all(or most) of these things can be ordered online at a fraction of the cost(and safer) than the ones at petcosmart. 
I am starting whole prey, too. Good luck, I look forward to hearing how she takes to it!
