Pet trait (The Sims 3)

Pet Traits are included in The Sims 3: Pets. They work like Sim traits, by defining a pet's personality and fitting the pet's reactions to it. While some pet traits are available for all pets, some are only available for horses, some are only available for cats and dogs, and some are only available for dogs. After picking three traits for your pet, you can train behaviors so they develop a "trained" trait with a green box around the new trait.

Trivia

 * Since Horses are not featured on The Sims 3: Pets (Console), all pet trait that are exclusive for horses will not be available on The Sims 3: Pets (Console).
 * Pets created in CAS have 3 traits, but can have an additional 2 traits added through reinforcement.
 * Pets adopted or bought (in the case of horses) can have 1 to 3 traits. As with pets created in CAS, additional traits can be added through reinforcement.
