Book excerpt: The House Rabbit Handbook coined the term house rabbit and continues at the forefront of rabbit care and appreciation. Packed with the collective wisdom of bunny-lovers and charming, candid photos of their pets, this fourth edition keeps pace with a more knowledgeable and demanding readership. This revision includes updated health-care and dietary information, accompanied by diagrams and photo illustrations, and chapters on understanding rabbit language, choosing a rabbit, and safety issues. A new section includes revised recommendations for rabbit space and how to creatively integrate it with human space. Fresh housing options described here include condos and Xpens. Exercise and ways to encourage it is the subject of another new section, covering how the shape of an exercise area can determine whether it's used, along with equipment and stimulating activities for rabbits. Also here are improved techniques for litter box training, bunny proofing, lifting and handling, grooming and bonding; behavior insights from expert caregivers; dealing with elderly, special-needs, and disabled bunnies; and much more.
