I would agree with @Ituri, this exhibit is by no means large, but it was fairly adequate for the Warty Pigs that lived here. It's also worth noting that the pigs have since been replaced by a pair of Crested Porcupines.
@Ituri African Crested Porcupine (Hystrix cristata) actually. Indian Crested Porcupines used to be exhibited across from the Tapirs until a decade or two ago, when they then became ambassador animals. sometime between then and now they switched to African Crested.
