Friends of Palm Beach County Animal Care and Control said on a Facebook post that for the first time in history their kennel is completely empty.
A video shows shelter staff wearing their masks, clapping and cheering in celebration.
Palm Beach County Animal Care and Control thanked shelter workers, foster parents and all those who adopted a pet.
According to a supervisor at the shelter, only "emergency surrenders" of animals, including cruelty and cases of domestic violence, are being accepted at the moment.
The shelter is not aggressively picking up strays.
