[@71452K] The Redwatch regularly goes past the no predator zone to look for missing mice, repour the Spoorwall, and generally do ranger stuff. Therein lie gigantic snapping turtles, wolves, bears, wolverine, owls, and all sorts of ridiculously large things that either want to (and easily could) kill you, or things unaware of you that could accidentally just step on you. Either way, beyond the Spoorwall is as scary for a mouse as a forest should be.
