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

Pretty good sorting game, more like Wilmot's Warehouse than Parcel Simulator. The main gameplay is about 10-15 hours, and it is 100% about manually sorting and categorizing packages with stamps by a slowly growing number of criteria. There is no automation, this is a leisurely sorting and organizing game. You reach the end of the game after serving about 250 customers, and you can continue, but the gameplay is about the same as any day before at that point.
Très appaisant
I must slay the pile
super fun and addicting game. my only wish is that you could sprint faster or use your xp to unlock something, even if it's not upgrades, just customization for things
I realy like this game, its cozzy and cute but pls, pls make it an option to toggle some features, I like to sort all my boxes at once and the conetction of 2 difrent parcils is sooo anoing first i have to wait to sort it till its dark and then i cant even put them together (dark and cold), so it comes often to the point that i get parcils returend. 2nd pls make it so that kids and other costamers do say there full name, had it so often that i had 3 same parcils and had to do trail and arror to find out with is the correct one. love the game keep up the good work.
Pretty nice game that just clicks. Soothing and pleasant. The only complaint that I have is that character should have a faster walking speed, he barely moves. And I know, that it would seem silly, but maybe some memo on the wall on what all the warnings mean? It is kinda simple, but sometimes the brain puts out blank, and I think that if there was some kind of remainder it would have been nice. Didn't meet any bugs. Only, closer to the end of the main plot I get two or three freezings, but it was no big deal – less than a minute.
very good. 10/10 will play again :)
Cozy. Fun. Relaxing. Just make some marshmallows, hot chocolate and play. I recommend a lot.
C'est super cosy ! On a testé avec ma meilleure amie et on vient de jouer 1h30! Moi, je dois aller dormir mais elle elle va continuer d'y jouer encore longtemps je pense x) Les graphismes sont super jolis, le sound design est super cool, et les personnages sont trop mignons ! On comprend vite ce qu'on doit faire, et le fait de débloquer des nouveaux timbres et de nouvelles pièces, c'est vraiment cool ! Si vous cherchez un jeu cosy avec vos copains, c'est idéal et franchement pas cher !
Fun game
