Background: I am a kid in elementary school. I have a pet cat, and I love soccer. I have to make a presentation in class next week, so I want to talk about my two most favorite things in the world: cats and soccer. 
Request: I need information about the Russian cat Achilles, who predicted the results of the opening soccer game between Russia and Saudi Arabia at the 2018 World Cup. I want to know everything about this: why he chose to make a prediction about the world cup, how he told people that prediction, and whether he got any of the details wrong.  I am not interested in predictions by other cats, or by any other animals -- just Achilles!
