Photo Release: On St. Patrick’s Day, National Zoo Animals Find Treats at the End of the RainbowWith St. Patrick’s Day just around the corner, animals—and their keepers—at the Smithsonian’s National Zoo’s Cheetah Conservation Station got into the holiday spirit. Animal care staff and aides created enrichment items—a paper-Mache mouse and Leprechaun hat—for maned wolves Siete and Diamantina. Inside were some of the wolves’ favorite treats, including frozen-thawed mice, red grapes and banana. These animals, which are native to central South America, are omnivores and will eat small mammals, insects, reptiles, birds, bird eggs, fruits and vegetation.
