The latest update brought the possibility to adopt a pet and take care of it via Feeding and Playing actions on the Pet page of the Inventory.
Share your impressions and eventual advice about the Pet System on this topic. 

To acquire a pet, you need to collect roughly 1500 gold and head to the exotic menagerie in Hellyon Undergrounds. 
If you are interesting in testing it but can't manage to get that much gold, DM me on discord.
