How Long Does It Take For Her To Poop ?

She Has 4 Mice In Her And How Long Will It Take For Her To Poop/

She'll poop when she's ready: some will hold it for a long time then BAM you'll find a huge surprise one day and others poop pretty regular. I wouldn't worry about her.

X2 I have one who poops every week and a couple who only poop after they shed or I clean the enclosures :)
She will poop when she wants to

Poop timing isn't too important. They poop when they want! You can keep feeding them even if they haven't pooped out the previous meal.
