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 cute, super cozy, super addicting ♥ probably not as fun alone as it is with friends, but would still highly recommend!
Very good game!
A wonderful 17 hour experience for me! If you enjoy cozy games and you came looking for things similar to the Arcane Library clean up game then this will definitely scratch the itch. I think this game is definitely unique enough that it'll challenge your organization skills and logistics. I did the entire experience alone, but it has multiplayer that you could try out and I'm sure with a friend it's a load of fun. The only real complaints I would have are ultra-specific, like super-ultrawide resolutions are functional but not selectable in the menu, and the Captain of the shipping boat IS SO ANNOYING BECAUSE HE WON'T MOVE HIS DAMN CRAP AROUND FOR OPTIMAL EFFICIENCY. Also, keep in mind you can only stack packages in certain ways, so while yes your Tetris skills will be put to the test, there are some limitations on what you're allowed to do. Either way this game was a ton of fun and I highly recommend it.
very fun and cute
fun and cute game, wish we had more instore customers, the heavy focus seems to be on the deliveries so I run out of space for those but have a lot of open space for customers who come to the counter
No notes, perfect game. Certifiably addicting, even after finishing the main story.
very casual and fun game to pass time whether solo or with close friends
Cozy, peaceful, no time limits, no real worries. Play at your own pace, truly an enjoyable game, can't wait to put more hours into it <3 W Devs, also can't wait for more features to make my job easier xD I'm going to start over and see if I never put the keys into the door, if I never have to deal with with frozen packages ;D Update, doesn't work T_T It was worth a try
쓰레기게임
This Game had so much potential... The idea and game design is really nice and has a very cozy atmosphere. Sadly the fun only lasts for the first few minutes. I was hoping the game would slowly implement more features like upgrades or store custimization. But it was the same shift over and over again... There was no way for the Player to actually have the shop organized which made this game very unstatisfying. There is no Way to sort the Mail by Name as the Shelfs cannot be customized with A-Z signs and by size is just impossible because there are way too many packages for each type of shelf. This is another VERY big problem. I get more packages than I can get rid of and searching for the right package is an absolute horror as the given information is too limited for the amount of possible matches! I really wish they used the potential and made this an organizational heaven and statisfying by adding a ID Card System to find packages faster and verify the customer. Having a normal amount of Packages. Adding Upgrades. Maybe A currency. Sorting Systems. More Info on the Packages like the Date it was received and maybbe by when it has to be picked up. Im really hoping I can come back to this game someday. But right now the game seems to be not really thought through or its just to early.
