March to the Zoo on this special day when all guests are admitted FREE! (Parking and regular attraction fees still apply.) Visit the Small Mammals Building to see prehensile-tailed porcupine, Guillermo. Now about 8 months old, he explores his habitat, with many enrichment items to keep him engaged and active.
