Feral Dots are Dots that appear in Blight on the map. Players must rescue Feral Dots and clear Blight off of the map in order to Hatch with some Dots at Habitats or in the Visitor Dots section.
Feral Dots can be of multiple levels depending on their Traits that you have unlocked. The higher the level, the harder the Dot will be to rescue. If Traits of your active Dot match the Feral Dot, you will have a higher Compatibility Boost increasing your likelihood to successfully rescue the Dot. You can view the Fral Dot's traits by tapping on "See Traits" on the Feral Dot Rescue screen.
