Jake's story is two-fold.
It tells the story of a kitten who lost his new "forever" home the day after he got it - but got his new, really forever home the next day. The story is first meant as entertainment for children.
Secondly, it is a reminder for those who get kittens or puppies to make sure it is permissible to have them. In Jake's case, "Patty" had a landlord who said a very resounding "NO cats!" But Miss Maggie's landlord said yes. Far too many babies are dumped or taken to shelters by those who get them, only to discover that they can't keep them.
The story tells how he got his final home, his kitty companion, Mini, and his innumerable antics, like learning to play fetch, and following directions in a way that shows him to be smarter than the average cat.
