Ferrets may tend to be oriented towards odors rather than vision, but
that doesn't mean visual enrichments are not important.  Ferrets are
colorblind, seeing only red and some blue, so make visual enrichments
graphic, contrasting light tones against darks.  Bring the enrichments up
close and at the ferret's eye level.  Lady Noir is enjoying a favorite
enrichment, "Kill The Monster," where a 99-cent oven mitt was graphically
enhanced with contrasting felt eyes and mouth details, providing visual
stimulation to the experience.
