This is morse code (meow is dash, nya is dot, and purr is a new word). Using a simple morse code translator, we can trasnlate this message to get the flag. (I apologize, I don't have my script on me, but it's very simple. Just turn the words into dots and dashes by using ```string.replace()``` and then take that output and use an online morse code translator to get the flag.
