Fort Wayne Children's Zoo in Indiana had a busy spring season in its lemur department. Female lemur Seiodin gave birth to twins on March 8.  Then, just two days later, her daughter Caera delivered a single baby! Seiodin's twin babies get their first look at the outside world in April (first photo below) and Caera's baby takes a cautious peek over mom's shoulder in the second picture. The video shows one of the twins attacking her big sister, Kushla.  At the end of the video, Kushla gets revenge on her little attacker!
