Sven Nordqvist creates his stories in an amazingly alive world, filled with multiple layers. The cat Findus is the perfect animal representation of the children listening to/reading the story, and the kindly but occasionally grumpy Pettson is of course a great parent figure. He doesn't keep his house particularly tidy, frequently gets caught up in dealing with urgent demands (chickens, cows in the garden, etc), but ultimately does do the important things, like make food for Findus. Sounds like a lot of parents I know!
Little details make Pancakes for Findus a delight for adults and children. As you read, you start noticing other things -- like the chicken paramedics carrying away one of the broken eggs!
This isn't really the first book in the series. Findus and Pettson have an earlier incarnation as Festus and Mercury (Mercury being the cat), published by Carolrhoda Books. They're even funnier!
