People adopt shelter animals for a variety of reasons, such as wanting to provide a loving home for a pet in need, saving an animal's life, supporting animal welfare causes, and finding a loyal companion. Adopting from a shelter also helps reduce pet overpopulation and can be a more affordable option compared to buying from a breeder. Additionally, shelter animals often come vaccinated, spayed/neutered, and microchipped, which can be attractive benefits for potential adopters.
