I just finished Homer's Odyssey the other day, and I finished Dewey this summer. Both really tremendous books. They are both available on Audible (that's how I enjoyed them).
Dewey is about a very remarkable stray cat who got adopted by a public library, and became a very central figure for a small town in Iowa, and went on to international fame. Homer is about a blind cat who adapted fabulously to his handicap and weathered the 9/11 disaster in New York. Both are really heart-warming stories and very good reads. I like them about equally. Both are probably appropriate for kids as well (unlike Cat Daddy and Streetcat Named Bob).
One major bonus of the Homer one is that on the audible track, there is about a half hour or so interview with the author and her husband (both central figures in the story) at the end of the book. They talk about Homer and the other cats, it is a really nice treat once you have finished the book. Another thing I really liked about Homer's Odyssey was how at the beginning of each chapter, the author finds a quote that sums up the upcoming chapter. That in itself is not unusual, and in many books is actually kind of pretentious and annoying, but these are actual quotes from "Homer's Odyssey", which make them kind of fun!
One nice thing about the Dewey book is that because the cat indeed was such an international star, you can find lots of video and pictures and stories and such, about Dewey, on the internet (especially youtube) after you read or listen to the book.
