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

Imagine if I could organize my room as well as I've organized this post office....what a dream. Too bad it's not nearly so satisfying in real life.
This is a rage bait simulator. I wonder if this was written by Ai because my pea brain, in fact, did not produce a singular cozy molecule of serotonin or dopamine during my- albeit short- play-time of just over 30 min, that I played this game. It's comedically easy for any and everything to catch the attention of my ADHD brain, so it really say's something that this left me wanting. The labeling system for the shipping dock was just a, "if you figure it out- great!", "if you don't... well I hope you like re-organizing" kinda thing. The three little shapes that are supposed to indicate where/what you're supposed to interact with, aren't visible through walls, and a completely unassuming color. A glowing outline that's visible through walls would be way easier to notice. Ever heard of labeling the thing your mouse is hovering over? Why don't the cats just tell me their name during the retrieval of their packages? If my brain could talk, it would probably use words like, "cortisol" and "vasopressin" in the description of it's endurance of your pay-walled psy-op of a program. It is tedious to have to hold the shift key to sprint, I would much rather it be a purchasable, permanent upgrade. I would've been happier to have been mugged with $15 in my pocket. spent another hour playing and i started figuring stuff out and it was a pretty fun time trying to figure everything out.

Wenn man das Game zu zweit spielt ist es etwas kurz, macht dafür aber unfassbar viel Spaß
I really, really loved this game, so much so that I continued to play it for a few hours after completing everything. There is just something so cute and relaxing about being a cat working in a post office :) Progress was well-paced and the mechanics were easy to learn. I chuckled a lot at how often the Fishercat changed where his home was (apparently he lives everywhere) and when customers would say "Its for my wife, Greg Upsettears." No wonder she is so upset, her name is Greg! :) Please make a Cat Mail Co. 2 where we can hand deliver the packages! That would be so awesome!
Cute relaxing game with no time limit
Amazing cozy game. Keeps your attention enough to keep interested but easy enough to zone out.
Es un juego muy entretenido, lo que si hay veces que tiene pequeños fallos en multijugador porque al segundo jugador se le bugean las cajas y si te dan varias a la vez hay algunas que no son visibles hasta que no las lanzas y se caen las que tiene encima o si el anfitrión de la sala las separa. Luego otro pequeño fallo a mencionar sería la cinta que esta a veces se bugea teniendo que poner la caja al final de esta para poder escanear el paquete y también hay otra cosilla pero es de menor importancia es que el movimiento de la campana para hacer que se vaya el capitán, pasado un tiempo no hace esa animación. Fuera de eso es un juego que me ha gustado y estaría guay una actualización en el futuro la cual te deje ir a otra localización y ayudar en esa oficina o alguna otra cosa para que alargue más el juego porque una vez limpias los montones se hace repetitivo, cosa que me apena siendo un juego el cual disfruto.
I spent 21 hours straight, only took overall maybe an hour break in total. Great game for the price, got all the achievements, will not be playing again solo, but with friends, probably.
