Pet Simulation refers to a type of video game or software that allows players to care for and interact with virtual pets. These simulations often include activities such as feeding, grooming, and playing with the pets, mimicking the responsibilities of real pet ownership. Players can usually customize their pets' appearances and environments, creating a unique experience. Many Pet Simulation games also incorporate elements of training and socialization, where players can teach their pets tricks or engage with other players' pets. Popular examples include Nintendogs and The Sims, which offer immersive experiences in managing virtual pet lives.
