After five months, Zara and Zuko are now parents to three piglets born on Friday.
Two of the warthog piglets are male and one is female. Zara, their mother, was born at the San Diego Zoo and came to Fresno in 2012. Zuko was brought to the Chaffee Zoo in 2013.
The mother and her piglets will not be on display to the public for two to three weeks.
