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

Super cozy game and very entertaining to play with friends or alone to pass the time. Throughout the game you uncover new rooms and baubles related to the previous postman which gives you motivation to keep going. Some packages can be a bit annoying to deal with (damn hearts) but otherwise the game is purrfect :3 10/10
i love this game soo much but omg my brain is melting theres no upgrades, so far from where i am in the game and every unlock feels like more stones on my path and theres no upgrades! as i mentioned before wich makes the challanges that come towards you feel kinda overwhelming
Game is fun, first 1 hour was 10/10 now with a big storage and like one day -3 packages but 20 new its just too much packages and then they come "yeah a package thats cold and fit on my bike" YES LIKE EVERY SINGLE ONE? I dont get 50 packages there lol to him to say no not this no not this YES TELL ME THEN. That ruined the cozy vibe for me :( annoying - not relaxing anymore AND ALSO WHY THE ♥♥♥♥ IS HIS MOTHER CALLED EREN AND XAVIER THATS NOT EVEN GIRL NAMES I SEARCHED MINUTES FOR GIRL MOTHER NAME
好玩 中期要很會空間整理 不然中期信件會越來越多 直到地圖全部解開才會開放全部功能大量縮減信件 適合喜歡殺時間的遊戲 不適合會3d暈的人
0/10 no invert Y option, will change review if this basic accessibility setting is added.
this game is amazing if you like organizing, stacking boxes and following clues to what mail people want to collect. like bitemarks, stickers, hot, cold and so on.... Game look amazing and i have not seen any bugs or crashes. Well worth playing
Cute albeit repetitive and a little too grindy. I thoroughly enjoyed it and would recommend to anyone who loves a good simulation/organization type of game (very akin to Unpacking). Playing solo the whole time I eventually reached a point where I had almost nothing to do, but I am unsure of how the pacing changes if you play in multiplayer. One of the classifications of parcels (the [spoiler]Lovers stamp[/spoiler] ) ends up being completely obsolete if you're good at placing the parcels on the ship for the correct destinations. I wish there was a little more control over how things unlock instead of cleaning up enough mail, but was a pleasant experience overall and I think it's fairly priced for the amount of hours it took me to finish the game. Editing to add that there are very little repercussions for returned or damaged parcels. I handed a customer a damaged one just to see, and they said nothing about it. Very low stress, though I wish there was a little more to it in that regard.
Nice and fun game. Calming as well
me like cat sort parcel
Me parece un juegazo de los típicos que pasa el tiempo rápido, me gusta que no tenga limite de tiempo en muchas cosas y te permita ordenar todo a gusto. Considero que podría mejorar obviamente recién ha salido, yo le agregaría quizás una historia que se expanda mas, que se pueda trasladar a otra isla a trabajar y se desbloqueen nuevas modalidades de archivo y etiquetado, que el barco se pueda modificar la ruta del viaje y el espacio con monedas o algún tipo de canje porque creo que luego de un tiempo se hace corto el juego, igual actualmente creo que lo mas útil seria tener en el menú una libreta que te vuelva a explicar que hace cada nuevo objeto que se agregue o la funcionalidad exacta de cada uno porque pese a que te acuerdes a medida que juegues para que es cada cosa, estaría bueno que exista mas si explica historia de cada isla o porque se envían pedidos allá, eso seria muy interesante si se les agrega mas personalidad a las cosas. En definitiva es un gran juego, tiene un muy buen punto de partida y mas si va evolucionando con el tiempo. Gracias por crearlo!
