Not sure if they found their kitties yet, so I'm reposting this "2 lost cats" ad from craiglist...

"I live by Coppergate and the Viking in Ballard, just up the street from QFC. My two cats, pictured below, escaped over night. I don't think they went far; they're too scared of everything that isn't a comfy couch. If you find them, please email me!"
(Cats are gray/white and orange/white. See photo posted on craigslist. Respond to email through craigslist.)
