One decent reason to feed outside the tank.

If the BP is dragging the prey across the substrate (assuming it's a type of wood, not paper), then you run the risk (albeit slim) of substrate ingestion.

*Shrug* I'm new, so I'm really just a parrot, repeating what I've heard. There may be absolutely no adverse effects to in-cage feeding.
