Ungulates are the most prevalent mammalian stereotypers (Bergeron et al., 2006). Oral stereotypies are the most common abnormal behavior of zoo-housed giraffes, suggesting that this species develops stereotypic tongue movements (Bashaw et al., 2001). Wild giraffes must use their tongues to remove and consume tree leaves (Baxter & Plowman, 2001); therefore, the saliva production may be high due to the oral stimulation and time involved in selective feeding patterns (Kearney, 2005). Feeding captive giraffes is a challenge. Their diet consists
