Rarest Pet Simulator 99 pets (lowest exists)
In Pet Simulator 99, supply is half the story. This page ranks pets by their Normal exists count, the number of copies the official feed says are sitting in player inventories, fewest first.
A low exists count does not guarantee a high price on its own, but it explains why some pets hold their value for years while others flood the plaza the week they release.
