Despite the casual and humourous tone, which I really think helps readers relate on a personal level, it was really clear how passionate the author is about what he does. The stories that he shares are never lacking in enthusiasm and as someone who appreciates random trivia I enjoyed reading the fact file for each animal. His writing is also deep and meaningful in that we get an insight into his own feelings towards certain aspects of his vocation and what being a veterinary surgeon is really about. Even from the introduction, readers get a real sense for his determination and passion. I would recommend this for all, not just animal lovers or aspiring vets. Easy reading too, not too technical or drawn-out.
