Mammals of North America is the latest entry in the Kaufman Focus Guides series, launched to much acclaim last year with Kenn Kaufman’s Birds of North America. This innovative nature series uses digitally enhanced photographs, rather than drawings, to help users identify each entry. The new guide, Mammals of North America, limits its scope to those wild mammals known to occur on our continent, and the result is a perfect gift for campers and avid outdoorsmen. With keys for recognizing every animal from the elk to the marmot, this user-friendly guide also includes a map of the area in which each animal is likely to live, as well as the size and appearance of the animals’ tracks. “For the most part, mammals are what we have in mind when we think about the thrill of seeing wild animals,” Kaufman writes. “Let a fox or deer cross the path, let even a chipmunk approach the group, and it will become the center of attention. The mammal trumps everything else.” Amy Scribner is a writer in Olympia, Washington.

What is it about sea turtles that make them so mysterious? Is it the laborious egg-laying process, in which thousands of females lumber up the beach to deposit their eggs? Is it their immense size? Their prehistoric roots? According to author James R. Spotila, the director of the Center for Biodiversity and Conservation at Drexel University, it is all of this and more. In Sea Turtles, he writes, “The seven species alive today are ancient reptiles living dinosaurs if you will swimming through our oceans just as they did one hundred million years ago.” Sea Turtles is a compelling look at these ancient creatures, which can live for decades and reach weights of up to 2,000 pounds. Spotila traces the history and life cycle of the sea turtle, as well as efforts to preserve the seven species, many of which have been hunted to the brink of extinction. Sea Turtles profiles several individuals and programs aimed at saving the turtle. Beautiful color photos and lyrical writing make this book a must-have for any nature enthusiast on your gift list.

Okay, so maybe you don’t know anyone whose true pet passion is the pig. That should not deter you from picking up The Whole Hog: Exploring the Extraordinary Potential of Pigs, a lovely yes, lovely book from the Smithsonian Institution. This well-researched and beautifully illustrated volume is crammed with facts about pigs, from the domestic pink pig to more exotic varieties. Author Lyall Watson displays a charming enthusiasm for swine (his childhood pet was an orphaned warthog called Hoover in honor of his vast appetite), and the book is chock-full of his own pig anecdotes from decades as a zoologist.

Watson’s love of this highly intelligent animal is contagious. “There is something cryptic about them,” he writes, “a mystery waiting to be resolved, a sense of intellectual potential that will not be denied, no matter how hard some people try to relegate them to the farmyard as ignorant oinkers.’ ” Read this book and you’ll never look at bacon the same way again.

Those who aren’t enamored with hounds can pick up The Cat Fanciers’ Association Complete Cat Book, edited by pet expert Mordecai Siegal. In addition to tips on caring for cats, this book delves into detailed descriptions of various feline breeds, from the standard Siamese and Persian, to lesser-known cats such as the Javanese and the Scottish Fold.

The Complete Cat Book’s pictures and descriptions of various breeds reveal that cats are as varied in appearance and temperament as dogs. For example, the Selkirk Rex, a breed first found in Montana, sports a woolly, curly coat similar to that of a lamb. The Scottish Fold gets its name from its ears, which fold forward and downward.

The authors also devote ample space to describing the characteristics of a pedigreed cat and outlining the show process. This book is just right for the owner of any feline, whether it is show-quality or simply a beloved housecat.

Naturalist and author Sy Montgomery leads a quiet life in rural New Hampshire with her husband until the day they adopt Christopher the pig. Small enough to fit in a shoebox when the Montgomerys bring him home, Christopher is undernourished, the runt of a large litter. Remarkably smart, irresistibly charming, he fits right in on their eight-acre farm, befriending the neighbors, who bring him treats and help the Montgomerys nurse him back to health. The Good Good Pig: The Extraordinary Life of Christopher Hogwood documents the friendship that develops between the author and this endearing animal. Explaining the appeal of her unusual pet, Montgomery writes, Everything about a pig makes people want to laugh out loud with joy: the way their lardy bulk can mince along gracefully on tiptoe hooves, the way their tails curl . . . their great, greedy delight in eating. Montgomery writes with skill and sensitivity about the challenges of caring for this formerly fragile animal, who now weighs a robust 750 pounds. Christopher has been profiled in USA Today and on National Public Radio, and Montgomery now shares his story in full in this unique and beautifully written memoir, already one of the most talked-about books of the summer.

<B>The Philosoher’s Dog</B> If your brow is high enough and your quest for a deeper understanding of the intricate bond between animal and human life is strong enough, <B>The Philosopher’s Dog: Friendships with Animals</B>by Raimond Gaita offers provocative insight. “The person who has rid himself of the need of others, who longs and grieves for no one, is not someone who is positioned to see things most clearly,” Gaita suggests, and he extends this need to include the love of animals. A professor of philosophy, Gaita uses what he calls a mix of “storytelling and philosophical reflections on the stories” to analyze mankind’s connection to animals. If you are as comfortable with quotes from Socrates and Kierkegaard as you are with tales of Jack the cockatoo and Gypsy the German Shepard, Gaita’s book offers both intellectual challenges and anecdotal treasures.

Geneen Roth’s The Craggy Hole in My Heart and the Cat Who Fixed It is a story of self-discovery and a struggle to fully and freely embrace the joys of living even while suffering its pains and sorrows. This time it’s a cat, Mister Blanche, a 20-pound male with a feminine name who looks like a “furry pyramid or a goat with curly stomach hair” who selflessly and wondrously fulfills the need. “Why love someone who is just going to turn around and either leave or die?” Roth agonizes in the early pages of the book, but it is through the actual loss of first her father and then Mister Blanche that she learns how losing a person or a pet you love can ultimately help you learn to love without fear, without reservation. Roth writes with candor and humor and does not spare herself the barb of her own self-awareness. Paralyzed by her fear of her cat’s death, she commissions an artist to immortalize Blanche by painting three portraits of him, and simultaneously makes a commitment to discover her true nature. “I figure it is good to cover all the bases: if I discover that my true nature is nothing to write home about, at least I will have a lot of nice paintings.” Still reigning: cats and dogs If your brow is high enough and your quest for a deeper understanding of the intricate bond between animal and human life is strong enough, The Philosopher’s Dog: Friendships with Animals (Random House, $23.95, 240 pages, ISBN 1400061105) by Raimond Gaita offers provocative insight. “The person who has rid himself of the need of others, who longs and grieves for no one, is not someone who is positioned to see things most clearly,” Gaita suggests, and he extends this need to include the love of animals.

<B>My Therapist’s Dog</B> <B>My Therapist’s Dog: Lessons in Unconditional Love</B> by Diana Wells is the story of how Wells, devastated by the loss of her son and sister, reluctantly reaches out to a therapist with a black Lab named Luggs. Wells has no insurance at this difficult time in her life, but the therapist accepts her as a client free of charge. To give something in return, Wells begins taking part-time care of Luggs, and gradually the dog becomes a bridge, connecting and comforting the two women as they each come up against more of life’s catastrophes. Wells is a historian, and she infuses her inspiring story with literary references and canine facts, exploring the bond that humans and dogs have shared for centuries. She quotes Emily Dickinson, for example, who wittily noted in 1862 that dogs are “better than human beings because they know, but do not tell.” Through her relationship with the therapist and her dog, Wells eventually overcomes her skepticism toward counseling and discovers the power of human (and animal) connections.
