Hmmm…if they and you are still in the same area, you can try sitting down nearby and eating a banana close enough to them that they can smell it. There’s a good chance they’ll come to you. If you don’t want to keep them as pets, I’m also in WA state and happy to help find a shelter in your area you can take them to
I was just passing through the state and had already left by the time I posted the pic :/ didn’t consider they could have been abandoned at the time… there were humans around camping though so maybe they just strolled off for some snack time
