While I enjoyed the cat stories, I didn't think they were particularly well-written. Not poorly written, mind you, but it is quite clear that the author is not accustomed to writing long works or well-experienced at stringing his anecdotes together. (As he is a minister, I assume he is proficient at the shorter works he must compose every week for his sermons!)

Most chapters end with a sermon, attempting to tie the stories of the chapter to a Christian lesson. These would have worked better for me if they had been gently worked into the chapters, but many will enjoy them -- I found them too preachy and an abrupt departure from the cutesy cat stories.

Moreover, I think I would have been a lot more impressed with the lessons he claims to have learned from the cats if one of them had been "Hey, all these outdoor neighborhood cats we love keep getting run over by cars -- let's bring them inside or at least spay the mothers so they stop dropping doomed-to-die kittens" instead of "You should keep loving even though sometimes it ends up hurting you." It's really sad to read the occasional mentions of these poor outdoor critters among the cute indoor cat stories, and doubly sad because the author, his wife, and his neighbors don't seem to think about it or how they could stop it. Giving playful lectures to the stray female cats about promiscuity is all very well, but a trip to the vet would have been rather more effective.
