Burial behaviour is the directed displacement of loose substrate over an object, deposit, or food item until it is covered. Its best-characterised form in small mammals is defensive burial, in which a rat displaces bedding with treading movements of the forepaws and shovelling movements of the head directed at a near, immediately threatening stimulus such as an electrified shock prod [1]. The response is suppressed dose-dependently by anxiolytic drugs, which underpins the conditioned defensive burying paradigm [2]. In domestic cats, litter use involves digging and pawing that move litter over the deposit, and cats with elimination problems spend less time digging than unaffected cats [3].
