# Pets

Pethereum is a metaverse where there are over 100 billion unique pets. There are 25 million different physical traits which specify pet’s rarity. When the color combinations are taken into consideration, the total number of unique pets reach over 100 billion. However, Color combinations do not effect the pet’s rarity. Pets, each of which is a blockchain-based NFT, take part in various games and earn Pethereum Crystals. Each pet has 8 different physical traits with several varieties that specify the rarity of the pet.

The factors that determine the physical characteristics of pets are as follows.

| Physical Trait | Number of Varieties |
| -------------- | ------------------- |
| Hair           | 10                  |
| Eye            | 10                  |
