My deepest condolences, I can't begin to imagine all you're going through.
There are most likely members in or near Seattle, please just keep this bumped near the top to give time for someone who can or knows someone who can take them in. I wish I could do more to help.
In any case, in the meantime, there are many people with gliders and cats, so maybe they can offer advice on how to go about their care until you find a home for them.
