Horse

Horses are pets which will be featured in The Sims 3: Pets. While custom content creators have made horses for The Sims and The Sims 2, this is the first time they have been included in an expansion pack.

The Sims 3: Pets
Horses will appear with traits. Sims will be able to ride horses to their destination, and horses will be able to push or kick Sims out of their grip. Sims can even die from falling off too hard. Also, judging by the official announcement trailer, horses can befriend other animals such as cats and dogs. It also appears that horses will be able to be entered in competitions. Also, there will be 5 different breeds of Horses. A herd of wild horses can sometimes be seen running through the town.

Trivia

 * The new town that is going to be shipped with Pets, Appaloosa Plains, is named after a horse breed.
 * The horse is the biggest animal, for now, featured in The Sims Series.
 * The Grim Reaper is seen in the trailer riding a horse into a portal. This may be a new feature for when a pet dies, as the Grim Reaper arrives and leaves via a portal.
