Newt was walking through the streets of London with his briefcase in hand. He had gone out to buy parchment, a quill and tint that he needed. He felt a bump on his leg and looked down to find a black cat looking up at him. It looked very thin, malnourished, even. It started following him around. Little did he know it was an Animagus.

Newt leaned down, taking a look at the cat and petting it gently.
