Hello all yah blood experts out there!

(anyone who knows these answers, lol)
I am wondering, my blood girl(20 inches) just had her last meal yesterday(well actually at 1:48 AM). It was her 4th meal with me. She is eating frozen thawed adult mice. I am wondering, she has not pooped yet. Im a little concerned. How often do bloods poop? Aswell, if i continue to keep this rate going, how many sheds should she have and how often? This rate assuming i increase appropriately with size increase. Thanks.
