Scents can be applied to pre-approved browse or enclosure "furniture" (rocks, walls, perching). Use sparingly to avoid possible over-reaction, especially with prey/predator scent. I found that even just touching my bare clean hands to various places without any particular scent being deliberately applied was investigated thoroughly by polar bears later on. Scent enrichment shows best results if used infrequently.
