Updating pet listings can vary a lot from organization to organization according to their own sets of processes. Generally, Shelters update their listings as soon as their new animals are ready to be adopted.
As Adopets, we advise you to check the Shelter website or public pet listing page daily, making sure you can browse through new pets and submit adoption applications when they become available.
