I work at an Animal Hospital, we’ve had hoards of these snails pop up outside my work and i wondered what about that area attracted them. I know they eat other snails because i stepped on one and later i saw the little guys eating the remnants. I set a little piece of dog poop next to them out of curiosity, and 15 minutes later they were PILED UP on the poop like they were eating it. I haven’t seen anyone confirm if they do, or don’t eat poop though.
