Cannot add much to what Deb said except to reiterate, that a very young BP is probably not even on FT yet.

Some take sooner than others, but chances are you got a live feeder, it went through a very stressful change, so no wonder it refused.

The owner or your store needs to rethink the animals being sold/kept if they are not willing to meet the snakes' needs.

Unless they are willing to stock FT eaters only, then they cannot have a policy such as this one.

I wish you luck with the second one, but the only recommendation I could give is to offer a live hopper mouse and see how it does.
