Have Cauldron Born be classic zombies, need to destroy the head to kill, infectious, etc. Have infected zombies created by Cauldron Born or other infected zombies be weaker and rot at a normal rate so they cease to be a threat after a week or so. So a few Cauldron Born created by really nasty ritual and they roam around causing local outbreaks that can usually be put down but then another one comes by and it starts again. Thus gives the PCs a reason to go out adventuring, looking for the Cauldron Born to stop the outbreaks.
