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 have so many critters and I tell people about them constantly. Still gonna make a card. Well, prolly more than one. I don’t think all my animals could fit on one. I have 2 dogs, 2 cats, and 12 ducks. They are all my children and I love them more than myself.
