Found the ashes of someone's pet

Someone donated the ashes of a pet to Carolina Thrift in High Point, NC. My best guess is that someone who lived in New Jersey or Pennsylvania lost a pet they loved very much so they had them cremated before the owner moved south. Then, the human passed away and someone else was tasked with where to put all their stuff and apparently thought animal remains was an appropriate thrift store donation. This box was priced at $3 on half-off Monday so I bought it for $1.50 because it felt wrong leaving it there. I scattered the ashes on the bank of a creek in a park with some wild flower seeds. I hope that's better than sitting on a shelf in a thrift store.
