Cat Steven is a typically-colored calico kitten, being predominantly white with orange and bluish-black patches. Her eyes are blue, with the right eye scarred closed by an unknown cause.
Cat Steven was one of an abandoned litter of kittens. She seemed to be the courageous one of the bunch, as despite their situation, she briefly left her litter, either to explore or to find someone who could help her and her siblings.
After finding and rescuing her and her siblings alongside Steven, Garnet decided to adopt her, noting that there was "something about her" and that Garnet had missed having someone "cute and vulnerable" to care for.
Garnet was originally going to call her Steven, but when Steven asks if that would get confusing, Garnet decided to call her Cat Steven.
As of Steven Universe Future, Garnet is holding Cat Steven in the family portrait where Rose Quartz's painting once hung. She is also seen holding Cat Steven many times and even trusts Cat Steven to go outside in "Snow Day". She is also seen taking Cat Steven to work in Steven's car.
Upon seeing Cat Steven outside Vidalia's garage, Steven instinctively decided that he and Garnet should follow her, causing them to find where her siblings were. After getting them out of the rain, Steven got Cat Steven's siblings into an animal shelter's foster program so they could eventually get loving owners and homes, and later adopted Cat Steven alongside Garnet.
She appears to be on good terms with Lion, as she is seen at the end of "Pool Hopping" sleeping on top of him, and attends Garnet's wedding on his head in "Reunited". In the KaBoom! comics issue #23 Lion took a rather motherly role to Cat Steven bringing her lizards for food and grooming her.
She seems to trust Greg, as she allows him to hold and carry her without protest after the Beach House is partially destroyed in "Reunited".

- Her name may be a reference to the singer Cat Stevens.
- Her single blue eye may be a reference to Sapphire. This is further supported by the fact that like the future, a cat is unpredictable.
