Can I just say "pity about" instead of "take pity about"?
To take "pity on" someone means that you feel sorry for them and try to do something to help them in some situation. "Pity about" is used to say that you are disappointed about something. So in this case, we can only use "pity on" because the Police Officer feels sorry for the cat and helps him to get inside. Ex: It's such a pity about the weather or we could go to the park. Ex: My teacher took pity on me because of my poor grades and gave me extra credit work.
