This was summer 2021, Sunset (as a previous Inner Sunset resident, this being west of 19th, I almost wrote “Outer Sunset,” but our host greatly preferred “Sunset,” as “Outer” meant quite a few blocks closer to the ocean), where the plastic sleeve is to protect from the fog/descending mist/marine layer characteristic of that microclimate. What caught my eye what information was included and what was not: why would the microchip and reproducibility be salient, but name and dietary preferences be not? I believe this is the first lost pet sign I have seen suggesting it be recorded with a handheld device by the concerned reader: “Take a photo of this flyer.”
