When Springfield's Sanctuary City was active, a few of the homeless people who tented there had pets. Only one person actually brought a pet into homelessness-- a woman whose white rat rode her shoulder. Everyone else found their pets, who were as homeless as they were. Steven had a kitten he discovered in an abandoned building which he tucked under his coat in the daytime and cuddled with at night. He still had his kitten when he found a place to stay.
Over at Change.org, Shannon Moriarty has a post about homeless people and their pets. Pets can be lifesavers for homeless people-- a live being who cares about you and needs you can keep you from giving way to despair-- but can also threaten their lives because pets are not allowed into homeless shelters. And it goes without saying that the life of a homeless animal is not easy, either.
Only two homeless shelters in the U.S. allow pets. Read more about it at Change.org.
