We fostered for Seattle Humane and they are extremely professional! Had a lot of resources available for foster parents and was a great organization to work with. We ultimately adopted from another organization since we couldn't find the right fit at Seattle Humane but I would definitely recommend them as another rescue to adopt from!
Got our sweet little Cleo from Seattle Humane in Bellevue. Large, transparent organization that accepts a ton of transfers from high kill shelters out of state. I can't say enough about the organization.
