# Purrstige Traits

Every CryptoKitty is born with a set of [48 genes](https://guide.cryptokitties.co/guide/cat-features/genes). Some of those genes are expressed visually; we call those Cattributes, and they define your Kitty’s art, like what shape of ears it has. Others are hidden, and can be found using third-party tools (we’ll hook you up with those later in the article).

Purrstige Traits are a very special kind of Cattribute. They’re challenging to breed, rewarding to unlock, and create some of CryptoKitties’ coolest looking cats.

## **What are Purrstige Traits?**

Purrstige Traits are Cattributes that are only breedable for a limited amount of time. Every Purrstige Trait has a special recipe that needs both Cattributes and hidden genes.

To breed a kitten with a Purrstige Trait, a player needs the right combination of Cattributes and hidden genes in the two parent cats.

## **Why breed Purrstige Traits?**

Breeding a Purrstige Trait can be challenging, but it’s rewarding too. Because Purrstige Traits are time-limited, they’re particularly rare — and especially valued as a result.

Plus, Purrstige Traits are always a nice visual treat, creating some of the game’s most beautiful and unique cats.
