Cat Mail Co Map & Destinations

Cat Mail Co takes place on a charming archipelago inhabited by cats. Your home base is Cat's Island, where the struggling post office serves as both workplace and narrative hub. As you restore postal operations, new destinations unlock — expanding delivery routes, increasing income, and revealing more of the island world's geography and secrets.

The in-game map accessible during stamp mode shows available routing destinations. Check it whenever applying destination labels to ensure parcels reach the correct island. Our Package Handling guide explains how map data integrates with the labeling workflow.

Cat's Island is your starting location and primary workspace. The post office, dock, customer counter, processing equipment, and initial storage shelves all sit here. Local deliveries — parcels addressed to island residents — never leave Cat's Island and require short-distance delivery rather than boat transit.

Most of your first days are spent entirely on Cat's Island, mastering the core loop before any expansion unlocks. The island gradually reveals additional areas and NPCs as story progress advances through processed mail and customer conversations.

Port Windy appears on the map as an early transit destination for outgoing boat shipments. Parcels routed to Port Windy require correct weight stamps and destination labels before loading at dusk. It represents the first step beyond purely local deliveries into the broader island network.

During the demo and early game, Port Windy is the primary external destination. Organize a dedicated transit shelf for Port Windy packages to streamline evening boat loading. Incorrectly labeled transit mail returns damaged, wasting rework time.

Sunny Shores unlocks through the Summer Room upgrade — the second-highest priority progression milestone. This destination offers higher-value routes where every correctly processed package generates more revenue than standard transit mail. The economic boost from Sunny Shores access changes your post office from break-even to profitable.

Dedicate a right-side shelf exclusively for Sunny Shores packages after unlocking, as recommended in our Progression guide. The Sunny Shores video guide shows the unlock moment in actual gameplay footage.

The Summer Room is both a physical expansion to your post office and the gateway to Sunny Shores. Upgrading unlocks additional workspace and new routing options simultaneously. The room provides much-needed processing area as parcel volume increases beyond what the original office layout accommodates.

Invest in the Summer Room earlier than you think necessary. Players who delay this upgrade struggle with clutter and miss Sunny Shores income during critical early-game days when currency for further upgrades is most needed.

As the narrative mystery unfolds, previously inaccessible island areas may open — particularly during night shifts when moonlight reveals hidden paths and properties. Night-unlocked areas tie directly to the missing postmaster storyline and special moonlit package routes.

Track story progress through customer dialogue and unusual mail. Our Night Packages guide covers evening exploration, and the Walkthrough maps the daytime discovery path.
