I would guess that the breeder didn't even use hides, just had them in a small rack (privacy from the surrounding sides of the rack).
Before you order, measure roughly the size of this coiled snake & add some space- you can always pad a hide that's a little too big- just something that will work for a while. BPs are snakes that often like "back pressure"- so they know predators can't sneak up on them- they feel safe.
Yes, she's FINE without a meal for now- she just refused a meal & she's still not settled in. See my previous post. And whenever a snake refuses a meal, always wait about a week before offering again, because constantly offering food just stresses them into refusing longer.Snakes are not designed to eat all the time- fasting is what they do for survival, & they're good at it.
