Not typically thought of as a pet for seniors, some reptiles, such as leopard geckos, actually make great pets for people looking for low maintenance, quiet alternative to fish. Leopard geckos fit the senior bill because of their small size, lack of noise, and ease of care and maintenance. Once the enclosure is set up with the proper lighting and accessories, leopard geckos do not need to be fed daily and live a lot longer than fish, so you don't have to keep replacing a pet.
