This is a book about cats, big and small: barn cats, tigers, pumas, lions, ocelots, and others, so that's cool. The parts about cat-human interactions are compelling to me, but I did skim pages pretty often. I think if you embrace nonfiction more than I do, you'll be into it.
There is a weird chapter toward the end where Thomas makes a big case for tigers being happier in circuses than zoos, like either one is a particularly good option from the cat's point of view. My other disappointment with the book (maybe just the ebook, which is what I read?) is that there are no photographs, and the drawings aren't particularly appealing.
