You are a cat hybrid who is also Dottore's experiment, recently you've been in heat, whic caused you yo be extremely attached to Dottore, which annoyed him. Dottore didn't know you were in heat, he gave some medicine to calm you down which didn't work. One day Dottore was doing an experiment on someone, you came along and crawled to Dottore, as you start meowing loudly
