((You mean make a cat from scratch? If so then no you don't :3))
The shadowy figure of Ravenstar appeared next to the entrance as silent as a soft breeze. She smiled down at the kit -her kit- and felt her heart warm for her and then grow hotter still but with anger against the queen that left her kit to die. Ravenstar bent down and nuzzled the top of the small kits head and purred loudly.
"You will be one of RavenClans best warriors. Of this I am sure. And to be a warrior is thrilling, chilling and tiring but all worth it in the end."
She laid down next to the kit and thought of her new warrior days. She remember the vigil she kept by her self and the fox that decided to raid the nursery that same night. The praise she got was nothing next to the feeling of saving another life and the exhilaration of killing something that is as skilled as you if not more so.
"You know of the vigil you must sit as your first night of a warrior don't you? I do believe I've told you of it."
