Gneiss

Gneiss is a she-cat kittypet that's past effects her actions.

Kithood
Gneiss was born a rogue with her sister, Carrie. Her mother soon abandoned them by the side of the Thunderpath. Gneiss and her sister waited there, too young to go out on their own. A twoleg came and took the two she-cats to a shelter. Soon, a beautiful twoleg she-cat came and took Carrie. Later, a tom twoleg took Gneiss. He already had another cat that he got from the same shelter moons before, an orange Abyssian named Alex.

Kittypet
Alex and Gneiss fell in love. The shelter lied about getting their cats fixed, so they could have kits. Gneiss soon had two children, Heather, and Teak. Gneiss freaked out when she realized that Heather was having a hard time learning, and was echoing words. Gniess knew that her mother abandoned her because she was imperfect. And Gniess wanted to do the same with her own offspring. Alex begged her to just change Heather's name to Echo. One day, it got to her, and she forced Alex to come along and abandon them in the forest. Which they did, much to Alex's dismay. Gneiss realized it was a mistake and later she went to the clan with Alex to apologize. Their kits were now warriors, Echoflight and Teakburst. Their kits accepted their apologies, and Gneiss could sleep easy.
