Ferrets are highly intelligent creatures that are rated in learning-set experiments to be as smart (or smarter) as primates of the same size. Learning itself is a form of enrichment, and the modification of learning-set experiments--those that challenge the intelligence of a ferret--can be used to enrich a ferret's life. Carbone, Amber, and Lady Noir are using olfactory senses to find the treat hidden within one of a series of plastic eggs in an application of the "Be An Egghead" enrichment. http://homepage.mac.com/billgruber/fml/3ferrets.html Bob C [Posted in FML issue 4201]
