[DC] Travel to Gotham and Become a Cat

What would happen if you woke up and found that you were a cat? A man woke up and found that he had turned into a kitten. Fortunately, a kind British housekeeper came to help him and saved him from starving to death at the beginning. Just make peace with what you've come to, since you've already traveled through time and become a cat, so why not be a good pet and give it to your boss in his old age... Wait. What does it mean that your young master is an unlicensed vigilante who wears tight clothes and goes out to beat criminals in the middle of the night? No, I want to play too. So, the cat who tried to follow him out secretly was caught by the scruff of fate...
