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. 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 only 5 different breeds of the Horses.
