Ms Mann said the staff were so touched by the note, they decided to do everything in their powers to reunite Lilo and her family.
“We all cried reading the note,” Ms Mann told the Washington Post.
“We see a lot of sad stuff every single day, but it just really hit us all. The last line is gut-wrenching.”
The shelter began their search for Lilo’s family with a social media post on Jan 24 offering to “help in any way we can” without judgement.
Within a day, Lilo’s owner had been located and been to visit the shelter.
“There was not a dry eye in the room,” said Ms Mann, adding Lilo was ecstatic to be reunited with her owner.
The woman has not been identified to protect her privacy, but the shelter said they asked her specific questions in advance to verify she was Lilo’s owner.
“We had some private conversations, and she was very grateful,” Ms Mann said.
She added: “I told her: ‘you’re not alone. There are so many people out there that are dealing with homelessness right now. It’s an awful thing to have to go through but there are resources and people who care.’”
