All pets have graphics (sized 48 by 48 pixels). Pet graphics are entirely aesthetic and don't affect the pet's abilities in any way. (ex: a small pet graphic does not mean the pet will be small, wings do not mean the pet will fly, etc.)
Randomly generated pets use standard pet graphics, and players have the option to upload brand new custom graphics into the game.
There are 15 standard pet graphics in the game.
Custom Pet Graphic is a Favor service that allows users to upload and use their own graphics. It costs 500 Favor to change a standard pet graphic into a custom pet graphic. Note that this change is permanent; a custom pet graphic cannot be changed back into a standard pet graphic or another custom pet graphic.
For an unofficial list of uploaded custom pet graphics, see List of custom pets.
