Any novel stimulus which evokes an animal's interest can be considered enriching, including natural and artificial objects, scents, novel foods, and different methods of preparing foods (for example, frozen in ice). Puzzles that require an animal to solve simple problems in order to access food or other rewards are considered enrichment. An animal's environment may also be enriched by the presence of other animals of the same or different species.  A stimulus can be considered enriching even if the animal's reaction to it is negative, such as with unpleasant scents, although stimuli that evoke extreme stress or fear should be avoided, as well as stimuli that can be harmful to the animal.

Enclosures in modern zoos are often designed with enrichment in mind. For example, the Denver Zoo's exhibit Predator Ridge allows different African carnivore species to rotate among several enclosures, providing the animals with a larger environment and exposing them to each others' scents.
