Cat Mail Co. has you working at a post office, serving humanoid cats. The smile on each of their faces when you take their order in or get them their parcel should be enough reward for your work.

If it's not, the game also offers a bunch of Achievements that you can earn to give you something more tangible than the happiness of virtual felines. The list of Achievements isn't very long and is quite doable. To help, here is how you unlock each one.

Every Achievement In Cat Mail Co.

Piles of packages on a boat in Cat Mail Co.

Guide

Heave Ho

You have (correctly) identified a heavy parcel.

Early in the game, you get access to the scanner. When a customer brings in a package, you use the scanner to check the parcel for anything notable. Sometimes you learn that the parcel is heavy. Once you do, stick the weight sticker on it.

Iced Whiskers

You have opened the cold refrigerated room.

After several shifts and lots of points scored, you unlock the key to the refrigerator room. The key will be by the counter. Use it to open the fridge room in the side hallway.

Be Careful

You have (correctly) identified a fragile parcel.

When you scan a parcel that has been brought in and see an image of a glass, put the fragile glass sticker on it.

Cats Don't Belong In Water

You fell in the water.

There is water at the back of the post office, where the boat enters. Drop into that water.

Keep It Cold

You have (correctly) identified a cold parcel.

Once you access the refrigerator room, certain packages will need to go in there. When using the scanner, you will see a little snowflake. When you do, slap an ice temperature sticker on it.

From Cats Island With Love

You have placed 1 decorative stamp.

In the sticker menu, you will notice a section for decorative ones. Put one on a parcel.

Until Shipment Do Us Part

You have (correctly) identified a "lovers" parcel.

At one point in the game, you unlock the 'lovers' packages. When you scan these and see a love heart, stamp them with a heart.

Night Vision Activated

You have opened the dark room.

Play far enough into the game to gain access to the dark room, then enter it.

Float Mail Co.

You placed 30 parcels or more in the boat.

When the boat arrives and you remove what he brings, you need to fill it up. If you use fairly small parcels, you can get more than 30 on.

Stamps Hobbyist

You have placed 10 stamps on the same parcel.

Take a parcel and put a bunch of decorative stamps on it. If there are ten in total on the package, you get the Achievement.

As Good As New

You have repaired a parcel.

Once you collect enough packages from the big pile in the main room, you will eventually gain access to another room. Here, you can place a damaged parcel on the bench and click the cardboard next to it to fix it. Damaged parcels are typically darker and look visibly rough.

Take Off Your Furr

You have opened the hot heated room.

After you progress far enough into the game, you gain access to the heated room.

You have (correctly) identified a hot parcel.

Once you've unlocked the heated room, you can use the scanner to identify a package that needs heat. Once you do, slap the hot sticker on it.

You have stamped 500 stamps on parcels in total.

Keep applying regular and decorative stamps to parcels until you reach 500.

Sunbath Siesta

You have opened the light room.

If you play the game enough, you get access to the light room. Once you have it unlocked, enter it.

A Well Deserved Retirement

You finished the story and liberated the old postman.

Beat the game.

All cleaned up

You emptied the pile.

Get all the packages from the pile in the main room. Not every package in the pile is available straight away, so you won't get this Achievement until the end of your playthrough.
