Red Door Animal Shelter, Chicago

For centuries, a red door has symbolized a safe haven, and that's exactly what Red Door Animal Shelter is—a place of refuge for cats, dogs, and rabbits in need. This no-kill shelter provides a cage-free environment so that animals can experience a homelike atmosphere as much as possible. After spaying or neutering their rescued four-legged friends, Red Door places them for adoption, relying solely on private donations and grants to cover costs.
