Perhaps Amazon Defines "Nonfiction" Differently?

I like to read a lot.  And I tend to prefer non-fiction.  Since I order books through Amazon fairly often, their sophisticated systems have detected this, and occasionally send me emails with offers for more non-fiction books.

Today, I got this one:

Notice that "Squirrel Seeks Chipmunk: A Modest Bestiary" is the top title this week in Nonfiction.

From this, I suppose we must conclude one of the following:

1. This "new collection of keen-eyed animal-themed tales" which starts off "The cat had a party to attend, and went to the baboon to get herself groomed." really did occur (or is occuring) somewhere in the world.
2. Amazon has a unique and interesting definition for the word "Nonfiction".
3. Someone messed up

Which of the above seems most likely to you?

And if you chose number 1 and have read the book, where do these talking animals all live?  I've got a few questions about testing I'd like to ask of both the Sickly Rat and the Healthy Rat, that might make for an interesting debate.
