About

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.
A cozy, stress-free gameplay loop with no timers or penalties
A satisfying package handling system: weigh, stamp, label, and sort
A meaningful day/night cycle with magical nighttime mechanics
A relaxing “pre-crastination” experience focused on preparation and flow
A post office in a cat's world to organize and restore
Up to 4-player cooperative gameplay
A narrative discovered through sorting parcels

I loved it. This game scratched an itch I didnt know I had. It was fun even when playing alone. Though it was REALLY nervebreaking to get 100%... It took more time than I thought. Its repeating the same doing but its perfect for a no brainer and chill.
Such a fun, cozy, and relaxing game. I love that you play on your timeline.
Frustrating in a fun way. Sigh, time to say goodbye to that giant of a box, it's like an old friend at this point --- What do you mean there's two more, I just cleared that shelf!
Very cozy & cutesy game, have had lots of fun playing with friends over my four hours of play time thus far. Very nice early birthday gift from a friend of mine (birthday is tomorrow, 15 Jul.) Highly recommended to anyone who likes organization-based games or those that allow your mind to wander a bit while you get into the rhythm. Brings back fond memories of when I did postal work in high school.
Played the entire thing in single player and it was very addictive and very fun if organising is your thing. definitely recommend as i couldn't seem to stop playing the only issue i had was [spoiler] when trying to unlock the final room it felt like it took ages to clear the pile down and i was just obsessively checking to see if i could take parcels from it which sort of ruined the ending of the game [/spoiler]
靠這遊戲根本精神時光屋 會讓人一直玩一直玩一直玩不想停
Relaxing game, give it a try
Jogo confortável de jogar, com uma boa jogabilidade e uma histórinha fofa. A progressão faz tanto sentido que não da pra parar de jogar, como uma autista de férias digo: incrível kkkkk
I did not think I was going to enjoy this. But here I am after the game is over, hoping that the devs add more. I want more packages, more locations, more constraints. The game simply: Sort boxes so you can find what you need. If a person comes in asking for a package be-able to find it. When the boat comes for a specific location know where you stored all the items for that location. What the game is great at; you get to organize your way. No one and nothing tells you how to organize. You need to figure out what works for you. There are constraints on boxes, so have to be kept in the cold/hot/sun/dark room these rooms are smaller but you still have to keep them organized so you can find and move out ones that go our on the boat. Super great game and I hope the devs expand it more.
Super jeu, très addictif. Joué en couple sur 2 jours, nous n'avons pas vu les heures passer. Je recommande grandement ! Avec une bonne organisation et une bonne répartition, on peut très vite optimiser le jeu et avoir un rangement nickel. La difficulté est grandissante en jouant (+ de zones et de contraintes) mais je trouve que ça permet d'avoir un challenge constant. Sachant que c'est loin d'être notre premier jeu coop en couple, ni premier du style, ça nous a pris 8h à finir avec 100% des succès.
