A quiet island. A forgotten post office. And a mountain of undelivered mail.

You arrive just in time… or perhaps a little too late. The former postman has vanished, leaving chaos behind: parcels piled to the ceiling, customers growing impatient, and a once-thriving postal service on the brink of collapse.

One package at a time, you’ll bring it back to life.

Cat Mail Co. is about slowing down and enjoying the rhythm of small, satisfying tasks.

Incoming mail arrives by boat, and outgoing parcels must be carefully loaded for their journey.

Sort deliveries for the right destinations, or risk having them returned damaged. Take your time serving customers, organize your storage exactly the way you like, prepare for the next wave, and keep everything running smoothly as the post office slowly regains its former glory.

With each improvement, new destinations unlock, along with tools and abilities to help you manage the growing operation.

Every package tells you how it wants to be handled… but how you do it is up to you.

Weigh parcels to determine postage, apply destination labels, mark fragile or heavy goods, and decorate them with a variety of stamps. Functional or whimsical, every sticker you place adds personality to your work.

There’s no such thing as a “correct” way but just your way.

The post office doesn’t sleep… and neither do you.

As night settles in, moonlight reveals secrets. What seemed ordinary during the day may carry strange properties after dark, offering magical insight into how some parcels should be treated.

The routine continues, but in a magical way.

The massive backlog left behind isn’t just a task, it’s the story of the post office waiting to be uncovered.

Run the post office solo, or with friends.

With up to 4-player co-op, you can divide tasks, optimize your workflow, or simply enjoy the routine together. Whether you’re stamping, sorting, or loading the boat, teamwork makes the mail flow.
