The Oriented Strand Board (OSB) box was used by Rafał Stryjek et al. (2018), to show that wild Norway rats do not avoid predator scents when collecting food in a familiar habitat.
The box was comprised of two independent compartments with single entrances located on the same wall of the box. A black rubber bowl was placed in each of the compartments. Pieces of black cardboard were fixed to the bottoms of the bowls by a double-sided adhesive tape; the cardboard pieces were soaked with predator scent (during experimental sessions) or with water (in the control compartment).
Mazeengineers offers the OSB box.
