Cat Mail Co. Controls

Cat Mail Co. controls on PC

Cat Mail Co. on Steam uses keyboard and mouse for movement, carry, inspect, and placement. Native controller support is not listed on the store page at launch.

This Cat Mail Co. controls reference covers verified bindings from July 2026 PC play: WASD movement, mouse look, sprint, interact, and F for stamp mode.

Controls pair with the beginner guide for when to weigh, scan, and ring bells — inputs are simple; workflow is the learning curve.

Rebind through Steam if needed — Cat Mail Co. does not ship an in-game remapping menu at launch.

Keyboard and mouse defaults

Movement uses WASD. Mouse controls camera and cursor placement when applying labels and stamps.

Interact key picks up parcels, places them on the scale, feeds the scanner conveyor, and rings customer and dock bells when in range.

There is no combat or aim-down-sights layer — Cat Mail Co. inputs are postal sim actions only.

Movement and carrying

You carry one parcel at a time in Cat Mail Co. unless co-op teammates share the load across players. Sprint between dock, scale, and shelves during large incoming boat batches.

Physics matters while carrying — bumping fragile stacks can dislodge mail. Walk, do not sprint, through tight fragile aisles.

Vertical shelves reward careful placement; jump is not a core mechanic — position with mouse look and precise drops.

Interact prompts and bells

Context prompts appear at the weighing station, scanner conveyor, customer bell, and dock bell. Interact when the prompt shows — no button mash needed.

Customer bell starts a pickup or drop-off encounter. Dock bell confirms outgoing boat load after the captain manifest is stocked.

Scanner conveyor uses the same interact pattern: place parcel on input belt, read X-ray, apply fragile or heavy label at output.

F key stamp mode

Press F near a weighed parcel to enter stamp mode. Mouse placement applies postage stamps until scale color bands are satisfied, then decorative stamps if desired.

Exit stamp mode by canceling or stepping back — unfinished postage blocks valid shipping labels.

Stamp mode is the most fiddly Cat Mail Co. input for new players; practice on Cat Island standard mail before fragile rush hour.

Steam Deck and handheld notes

Players report Cat Mail Co. is playable on Steam Deck with community keyboard/mouse mapping or touchpad schemes until official controller support ships.

Stamp mode precision on a small trackpad takes practice — increase sensitivity or use an external mouse for long sessions.

Sprint and interact mappings should stay on separate buttons to avoid accidental bell rings while unloading.

Controllers and remapping

No native controller schema is documented at launch. Rebind keys in Steam Input if you use a pad for movement only.

Color band postage on the scale also displays numerically — stamp count is readable without relying on color alone, but bands are the fastest cue.

Co-op voice is external (Steam overlay). Cat Mail Co. does not require voice for any mechanic.

Mouse sensitivity matters in stamp mode — low sensitivity helps precise postage placement on small parcels.

Controls mapped to daily workflow

Morning unload in Cat Mail Co. is WASD sprint + interact carry loops. Bind interact somewhere comfortable — you press it hundreds of times per boat.

Midday customer bell play is slower movement, more mouse look for shelf scanning when clues mention ribbons or names like Quicknap.

Afternoon boat load repeats carry + careful walk near fragile stacks. Reserve sprint for empty-handed trips between dock and Port Windy shelves.

Night audits add walk-only aisles — toggle sprint discipline when moonlit parcels are in hand.

There is no native controller at launch — plan keyboard layout before marathon co-op sessions on Steam Deck.

• Do01Confirm WASD movement feels natural before first boat in Cat Mail Co.
• Do02Practice F-key stamp mode on a light parcel at the scale.
• Do03Test interact prompt at customer bell and dock bell.
• Do04Toggle sprint only on empty return trips during fragile stacking.
• Do05Remap Steam Deck controls if playing handheld at launch.

Control mistakes

Sprinting through fragile aisles knocks boxes — physics does not forgive even when Cat Mail Co. forgives timers.

Forgetting to exit stamp mode before picking up the next parcel wastes trips — muscle-memory F key saves seconds that compound across co-op sessions.

Accidental interact at the dock bell before load completes departs the boat half-empty — loader role should own bell timing.

Mouse sensitivity too high in stamp mode causes missed postage placement — lower sensitivity for small parcels on the scale.

Co-op control coordination

Four players sharing one Cat Mail Co. office means four interact prompts on the same bell — call "bell is mine" to avoid double-rings.

Only one player carries a parcel at a time per character — do not compete for the same scanner conveyor slot.

Host with lowest latency should own dock bell interact when manifest timing is tight.

See co-op guide for role stations that reduce input collisions on Cat Island.

Stamp mode (F key) should be one player per parcel — crowding the scale camera slows postage more than sequential weighing.

Practice sprint-cancel before fragile stacks — tap walk near delicate piles even when Cat Mail Co. does not punish timers.

Mouse-driven stamp placement benefits from a steady surface — trackpads work but slow F-key sessions on busy boat days.
