Video from the zoo shows the little pups pestering their mother, Rose. She gave birth to two girls and a boy in February.
Zookeepers say Rose is doing a great job taking care of the pups. They're still nursing but have begun to eat solid foods like fish.
Their dad, Wyatt, was brought in three years ago from Texas with the hope he would be a successful breeder.
