# Rarity [Pets](/gameplay/pets.md) in the Pethereum metaverse have various physical characteristics, such as feather types, ears, and more. There are 25 million combination of 8 different physical traits which specify pet’s rarity, excluding main color and secondary color. When the color combinations are taken into consideration, the total number of unique pets reaches over 100 billion. However, color combinations do not effect the pet’s rarity. The more common a pet's physical trait, the less rare it is. Pet rarity levels can also be seen in the marketplace. Rare pets can be sold for much higher prices. Pet rarity is determined by their 8 physical traits, and each trait can have a common, uncommon, rare, epic, or legendary rarity level. Thanks to this diversity, there are over 100 billion pets which have different physical traits and colours. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
