# 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. ![](https://lh6.googleusercontent.com/klE0ewEb3zFcQfpg47AYx0uMTSsIO_LuOzVVHaonfzM-D8I6ZgP8ezy0CA5z6MGKabxXryh-zVo8Xhfs_H9I31Flt_GwXtRb6XC6hDqa4SWie46xumYwoN04DQYhGvnyz7g_9m0V) ## **How do you breed Purrstige Traits?** Check out the [step-by-step guide](https://www.cryptokitties.co/blog/post/say-hello-to-clover) about how to breed the latest Purrstige traits**.** --- # 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.
