Grasskit

Grasskit is a dark grey tabby she-cat with darker grey flecks dotting her front, and green eyes.

Berrystar's Struggle
Grasskit first appears in this story. She is helping Chestnutkit clean out the moss, so that the apprentices don't have to do it. She is later seen in the same story play fighting with Seedkit, Aspentail's kit.

The Storm Coming
Grasskit appears in this story when Lightpaw and Treepaw get taken into the StoneClan camp as prisoners. She talks to them for a bit, and plays moss ball with them, before going off to join Dovekit, Chesnutkit, and Alderkit in a game of "Clans."

It is unknown what happened to Grasskit, as she does not appear in the next story, when her siblings become apprentices. At the Gathering Alderpaw and Chesnutpaw brag about their warrior names, but Grasskit is not anywhere to be seen, nor was it mentioned that she received Grasspaw as her name. She is presumed to be dead.
