You can if you choose to- send your pet out to travel the wider world!
If you click to send said pet on an adventure from the manage page... you will send your pet off to wander away and see what the world has to offer!
upon doing this some choices will disappear, you cant sell, trade, freeze, pound or release traveling pets. But while out they will possibly send back postcards, gifts, or messages each week (on monday) to your mailbox.
The items your pet can send home are (as of right now)-Ancient Artifact (https://legacy.atrocity-pets.com/picuploads/petmail/ancientartifact.png)--- Copper Coin (https://legacy.atrocity-pets.com/picuploads/petmail/coppercoin.png) ---- Glittering Jewels ---- (https://legacy.atrocity-pets.com/picuploads/petmail/glitteringjewels.png)Empty testtube (https://legacy.atrocity-pets.com/picuploads/petmail/emptytesttube.png)
