Cambridge Rat Watch gives sightings a block-level paper trail
A Cambridge-focused reporting site maps rodent sightings alongside public 311 requests, and can send submitted reports to the city.
- For
- Cambridge residents tracking recurring neighborhood rodent activity
- Worth noticing
- Public pins are rounded; exact Rat Watch coordinates are stored privately, while checked City filing sends details to Cambridge 311.
Field notes
The reporting form asks for a location, time, count, and observed activity, with device-location and photo controls. Its map can switch between pins and a heatmap and filter by time window or activity type. The page says Rat Watch pins are rounded while exact coordinates stay private with project maintainers; when City filing remains checked, details also go to Cambridge, where requests may become public. City 311 entries are service requests, not verified rat sightings.
