A British wrote in an American forum: I’m going to be quite mean now and spoil the ending for him. Just as their mother is about to return home the cat fixes everything with a load of weird machines, but he does come back.
The "cat" here appears to refer to "the person". But what does the phrase "the cat fixes everything with a load of weird machines" mean? Does it mean the person makes every effort to make his room tidy so that his mother will find nothing wrong with him?
