According to a side story told from Shampoo's point of view, she was mistreated as a kitten and did not trust anyone. One rainy day, young Kiri defended Shampoo from kids who were bullying her. When Kiri tried to pet her, Shampoo scratched her. Instead of retaliating, Kiri leaves Shampoo with her umbrella and returns with warm milk. That's when Shampoo realizes that Kiri was not like the other people that she had seen, who had been mean and heartless. Shampoo shed tears and was taken home by Kiri. Source: Wikipedia
