Peaceful Kingdom is a 501(c)3 animal welfare organization founded in 2000 to introduce innovative approaches to ending animal overpopulation in Knox County, TN, and surrounding counties. Since 2000, Peaceful Kingdom has implemented a subsidized spay/neuter program for pets of low-income citizens, an adoption center, a northern transport program, a pet tag making service, a trap/neuter/return program for feral cats, and Critter magazine for promoting animals available for adoption. Most of these programs have been adopted and scaled up by other organizations.
