Best time to hold would be at night since they are nocturnal, but it doesnt really matter.

BPs need a 12 on/12 off cycle. (NO UVB LIGHT!!!) balls tend to stress if they have to much light because they cant close thier eyes. i just leave my window open a little bit for 10-12 hours. (make sure they hav a shady hide to retreat to.)

change the bedding and do a complete clean once a month.but spot clean whenever needed.

if its a baby, every 5-7days(whatever size prey is the widest part of the snake). when it gets bigger(over 800 grams) once every 7-10 days

my bp tends to shed once a month

when they shed, increase the humidity to 70-80%, by misting, or putting a towel over the enclosure.

Hope this helps!
