Oh also... I have an idea: kitnapper that kidnapped Lionkit's sibling(s), possibly Mistkit. This kitnapper would be a rogue who is the grandchild of Valleytooth's mother, and is angry at the clans for driving his grandmother out for breaking the code by having kits with a cat from another clan, and proceeding to drop all but one of them into the river (another cat managed to stop her). That surviving kit being Valleytooth. And, of course, that grandmother went on and found another mate, had kits, those kits had kits and one of them is out dear kitnapper.
it's just an idea you don't have to use
