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

Immediately uninstalled the demo, then purchased the game! Absolutely love the simplicity and casualness! It's stressful, but in a rather enjoyable way!
Cat Mail Co. is one of the most relaxing games I've played. I love organizing and sorting packages at my own pace without feeling rushed. The adorable cat characters, cozy atmosphere, and unique day-and-night mechanics keep the gameplay fresh. The progression feels rewarding, and it's satisfying to watch the post office come back to life. If you enjoy cozy management or simulation games, I definitely recommend giving this one a try!
Cute and relaxing. No need to rush or worry about messing up. I completed the story and unlocked all of the rooms within about 15 hrs of play which felt kind of short, but you can still continue playing after if you want. This is great if you enjoy sorting things and geometric puzzles (for stacking the boxes the most efficiently). Not sure how it is in multiplayer - I think it could be fun to divvy up tasks. I love that it's cozy and relaxing but I think some kind of challenge mode could be interesting too or adding something to make it more interesting to play again after completing the story.
'Finished' the game, got all locations and rooms, and I can say I very much enjoyed the game. Sure there are a few bits and bugs that I would prefer fixed but they are so small. Like Giant boxes facing the wrong way when I put them down. I would also like a wider range of dialogue from the cats coming to pick up post, sometimes it's entirely unclear what package they want and it has me guessing between like 6 packages "My mom sent me to pick up the package. It has a cord around it." does not help in the least sometimes. Other than those I thoroughly had fun playing it alone, its cute and i like all the storage everywhere and trying to figure out the best method to store (Which usually included restickering locations to be more legible). Love it, and i hope itll be updated with just some qol updates?
A laid-back game that doesn't stress you out or put you under time pressure. It's a lot of fun with two players - you just have to resist the urge to clean everything up right away, or else the storage area will fill up quickly. The only thing that gets on our nerves a bit are the heart packages (soulmates), but with a little sorting, that’s manageable too. Highly recommended for anyone looking for a laid-back, relaxing simulation-style game! P.S.: The cats are absolutely adorable!
A cozy game with cats, how could you go wrong? Took me about 8 hours to finish story, but has infinite 'mode' after story is complete. Definitely worth the price tag.
Satisfying gameplay and nice music. The kind of game you can sit at and play hours on end. It satisfies some part of my brain that goes "Brrrrr" when I organize something. Well worth the money.
Adore this game, very chill and sorting with the lovers link has greatly improved with the update! Really love the shift from singe to multiplayer, bit buggy with the parcels at times but not enough to ruin the experience x
Cats are cute and game fixes my OSD mind
I bought this game for myself because I wanted a chill game. When my husband found out it had multiplayer, he asked if we could play together. I said sure, but I didn't think it was his kind of game. Apparently it is his kind of game. He wants everything perfect. We have a complicated organizational system and way of handling inflow and outflow. I don't know who this man is. Anyway, love the game, it's been fun listening to my husband freak out about missing a damaged package lol PS: Thanks for updating the companion package marker, much less tedious!
