Intonation (tone of voice) in other languages especially Russian and Slavonic is what can be the determining factor for if you are asking a question, if you are upset, happy, mad, excited, etc....
A literal interpretation is explaining something based on the literal meaning of the words or story, rather than the metaphorical meaning. For example, in Jack and the Beanstalk, the literal interpretation is that he actually climbed a beanstalk into a palace in the sky and found a golden egg. The metaphorical meaning is that he received wisdom, nurtured it, and it grew exponentially. Though the wisdom itself may not have been worth money, it led to wealth and success that could not be accessed another way. You see?

Answer: The mood is lighthearted because the comparison created is silly.
Explanation:
A simile is a figure of speech that proposes a comparison of two different things to create a more vivid description of something. In this example, the reference to the pillow shaking like "pudding on a plate" creates a playful image of the movement of the pillow caused by the cat.
The comparison is simple, not difficult to understand. And the mood, despite seeming a reproach to the cat, is not angry. It´s not happy either, as the author gets disturbed while sleeping, but the reproach is playful and still warm.
