Join the Animal Rescue League at the market and see if one (or more) of their available pets in need of a forever home would be right for you and your family.
You get a vaccinated, spayed/neutered, microchipped buddy, and the ARL gets the joy of finding a home for one more precious package. If you don't have the time or money for a pet, consider volunteering with the organization.
