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

It's a very cute cozy organization game. If you aren't good at organization it might get stressful, but I was able to set up a system that worked for me pretty easily. I wish there was something you could do with the final room, but that's okay.
This is a super fun game to play if you like management and organization. Graphics are fun and the game system makes a ton of sense
This is a really fun game! There's no time restraints on anything and luckily it isn't detrimental to your progress if you get anything wrong. Completed the story in 22 hours of gameplay and you can still run your little cat post office after the story is over! Absolutely perfect job simulator with added cosiness and kitties :)
Un giochino davvero molto rilassante, chill e carino! La gestione dell'ufficio è super simpatica e il fatto di non avere il tempo non ti mette pressione! Però mamma mia la pila di pacchi è infinita! 😃
A very cute and cozy package sending game. The new package qualifiers unlock slowly enough that you don't get overwhelmed but quickly enough that you don't get bored. The only modifier I didn't like was the soul mates one, because there's no way to tag packages so you can't note "hey this goes with this" if it's packages that have modifiers that means they can't be put together in one room. I guess you could use matching stickers, but even then you're running around all the rooms trying to find the matching sticker. Combined with the fact that you can only check what package is a box's soul mate at night, I quickly got fed up with that mechanic and simply tossed all soul mate packages in the corner and didn't bother with them at all. It would also be nice to have the game tell you why a package was wrong, because there were multiple times I was told I sent an incorrect package but have no idea why it was wrong. All I can guess is the boxes from the hallway/piles aren't necessarily marked correctly.
The game is super cute and I LOVE the organizing aspect so much
A wonderful cozy game that sets challenges and then gets out of your way. Unhurried, thoughtful, cute, and satisfying, it's always giving you things to do but it never feels overwhelming. The interface is pleasant, boxes thump nicely into place, and you can cover your packages entirely in smiling cat-face stickers if the mood strikes you. The multiplayer is fun, there always seems to be something to get done, and you're going to learn which of your friends has Very Particular Views about appropriate labelling and positioning of boxes.
Quick answer overall, game was very good and glad i bought it. That being said I'm not sure if my friend and I were really that good or, the game just became really easy about halfway thru. At first there was some challenge but after maybe 2 hours of playing everything fell into place and became extremely easy with no challenge. The magnifying glass to match the heart packages is nothing more than annoying and a waste of time. Don't even use it because you can usually just send all of one ports packages on the ship in one go anyway. Then, the 2nd magnifying glass to get rid of the purple mark is also just a waste of time and adds really nothing to the game either. Next, the point system is useless too. Why even give me a score at the end of a shift if it means absolutely nothing. Nothing to buy with the point, no scoreboard to see your best days/stats. That and when you make a mistake it barely even takes any points away so again, who cares about it. Lastly, the game is too short. We beat it in 7.9 hours and then the only thing to do is just endless mode. No going to another port, no rush of customers, nothing. Just really easy kind of of boring gameplay after that. Its like they give the player too many ways of getting rid of packages to the point that we were always all caught up. I know this seems like a negative review but it was actually fun and chill to just sit and sort packages. Will I play this ever again... Absolutely not, there's no point. A good update has to come out for me to even touch this again.
Wonderful little game. Would have loved to get some more tools along the way but overall a very chill and cosy experience.
