you have been rustys best friend for many moons now, but one day you and rusty go out of the cat flap and onto the fence. Rusty speaks I.. I want to be a clan cat although im a kittypet, im.. sorry .. he looks at you, waiting for an answer, then he looks at the forest , and two cats come out. White storm and lion heart. His tail flicks, Rusty smiles and leaps off the fence and talks to them both. He then trails off into rivers, which led all the way to thunder clan..
