Among the zoo's residents are some hoofed pasture animals - feral pigs, horses, sheep and goats.

Feral pig - Sus scrofa

The pigs at the zoo are feral. A feral animal is a domestic animal living in a wild state, for one or many generations. Feral pigs live throughout the state and are considered a nuisance by many people, a treasure to some, and fair game to others. The responsibility for their control and removal falls to the California Department of Fish and Game. Some feral populations of pigs have crossbred with European wild boars that were once released in California for sporting purposes.

Pigs use their unique snouts to root in the ground for insects, grubs, bulbs and roots. They eat leaves, nuts, eggs, small animals and carrion. Pigs don't sweat, so during warm weather they enjoy a wallow in mud to keep cool.
