While we have yet to receive information on how to unlock most merits, we do know what merits exist in the game, and what they do. There are currently 33 merits in total. The list may also be viewed on the Merits page of the site's Poppyopedia.
These Merits include:
"This pet has ultimately decided that the body and the mind are equally important."
"This pet will be able to wear hats!"
Black Hole Tum Edit
"This pet will be able to store a bit more food in their stomach. Oh: and will poop Dark Matter???"
Burps Moths Edit
"When fed, this pet may burp up a Moth..."
"This pet can see in the dark without the help of a tool."
"This pet can pull objects out of their dreams."

"This pet believes in friendship! And always agrees to relationship changes..."
Nature Channel Edit
“Your pet will be able to slip into and out of the Umbra at will - sometimes accidentally!”A Natural Channel pet will be able to access Umbra-specific events at any point in time. This is very useful for collecting Quintessence — a rare item used in many crafts, and used to build fireplaces. The only way for a pet without this merit to be able to access the Umbra would be to feed it Toadstools. It will probably throw up afterwards, though.

"This pet will no longer cast a shadow, and will no longer be visible in reflective surfaces! (Creepy...)"
