Seattle Audubon leads a local community in appreciating, understanding, and protecting birds and their natural habitats. We envision a healthy environment in balance with nature, where people enjoy, respect, and care for the natural resources that sustain the community of life. Seattle Audubon believes that keeping cats indoors, or allowing them to enjoy catios, is important in keeping beloved pets safe and protecting wildlife. For more information about Seattle Audubon’s work to protect birds, please see
