The book is at times very moving indeed. Includes stories of the real love and compassion of pets and other creatures. Like the elephant who was working by lifting tree trunks and putting them in holes (as posts) at the bidding of a group of men. She/he stopped, trunk in trunk at one point and refused to budge no matter what the men did. They finally realised a small creature (a kitten I think) had fallen into the next hole to be filled. Once they got the kitten out, the elephant immediately resumed her job.
This book also makes you think. If you have compassion be prepared to shed a tear at least once before the end of the book. You do realise that whether or not we could have been born into the body of a cat or a rat or an elephant, instead of a human being, (and I don't have any answer to that) the souls in other animals (because humans are animals biologically, too) deserve respect. If some get angry sometimes, then so do humans. And many show the most immense unconditional love you wonder how many humans could attain it.
