Why YSK: There are a lot of people these days living alone with pets and if anything happened to the owner, others may not know to attend to the pet. If something happened to you, a coma, an accident, death, etc, your wallet would be the first place anyone would look for info about you and it would probably be the fastest way to bring attention to your small loved ones.
I show my coworkers new pet pics almost daily because they seem to be genuinely interested in my menagerie. Especially the ducks lol. They’re from urban and suburban areas, so they’ve never really known someone who likes farming before.
