Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
No United States chart position — it charts only in the markets below.
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

So far the game is very cute and chill; I have only played it solo so far but I have been having a good time. The systems for labeling and identifying packages are introduced slowly so it isn't terribly overwhelming from the start but adds a challenging element later on as you progress. So far the biggest bugbear has been storage! But it's a fun puzzle to fit everything where it needs to go. I do wish locals would pick up packages more frequently to balance out the mail you sort out from the piles but it's a minor thing.
Playing using wine and on my steam deck. It's a very cozy game. There are some minor bugs but over all nothing game breaking that I ran in to. I hope there will be official steam deck support for the controller in the future otherwise rebinding the keys works well enough.

Really chill and fun game working in post office. Love no time crunch or limits, just taking your time doing your parcels.
You're supposed to send out the packages from the overflow. Not just the ones the residents give you. I have 19 hours of playtime and multiple files because I thought I was doing wrong. I may be the dumbest person in the world.
Its simple & fun. Playing with a friend is ideal. Im not sure id enjoy it as much solo.
[b] Якщо казати про загальні враження, то гра мені сподобалась. Цікава мультяшна графіка, звукові ефекти, максимально простий, але присутній сюжет. Також приємно грати в гру з українською локалізацією [Але деякі імена залишилися неперекладеними, маю надію, що це виправлять у майбутніх оновленнях]. Загалом гру рекомендую, не сказати, що це прям шедевр, але й не дуже погано.[/b] [spoiler] Окрема подяка Яні Слесарчук та Тарасу Коржику за створення української локалізації. :) [/spoiler]
a cute, cozy sorting and organising game. i haven't gotten through the massive pile yet but i'm slowly chipping away at it. i'm having tremendous fun with it. if you like this genre of game, this is a top tier example
Excellent game, very cosy, good little game mechanics, but most of all, cats. 100% in 11 hours!
A very interesting and calming game. It seems simple, but it's addictive from the first second. Bonus points for being about cats
我從一隻剛玩完Demo滿心期待的快樂郵政貓咪變成一隻過勞的郵政貓咪... 又從一隻過勞的郵政貓咪變成沒事做的郵政貓咪...我想這就是貓生吧... 這遊戲感覺像是倒吃甘蔗,前期要清掉堆積如山的包裹(可以解鎖房間),船運的空間也比較小,需要動點腦筋把貨物盡量塞滿,後期船運空間變大後郵局一下就清空了,有種莫名舒暢的感覺,但可惜的是後期解鎖更多房間後,能獲取其他城鎮的包裹數量變少了,反倒是船運載回來的包裹很多,客人來領包裹又只領一件,希望可以讓客人寄件跟取件的數量增加。 還有希望可以新增切換第三人稱的功能,有3D暈的朋友也想一起玩啊!!! 總結喜歡整理空間、分類包裹的人一定要買來玩~
