  • Features a full-color design with hundreds of schematic drawings, tables, boxes, key points, algorithms, and photographs for quick and easy access to information.
  • Addresses key topics unique to feline medicine and not currently covered in other books, including: insights and clinical advances attributable to the mapping of the feline genome; medical conditions associated with behavioral problems; managing the feline patient with co-existing and chronic disease; special medical problems and care considerations for the geriatric cat; environmental enrichment for the indoor cat; feline zoonotic agents and implications for human health; and shelter medicine and overpopulation solutions.
  • Provides in-depth information on indoor cats and senior cats, including timely guidance on meeting owners' expectations for longer, healthier lives for their cats.
  • Addresses the challenges of pet overpopulation, particularly the impact of millions of feral cats on public health and the environment.
  • Presents information written in the manner of expanded conference proceedings, delivering the latest insights and most current approaches to management of feline medical disorders.
  • Includes contributions from approximately 60 contributors, drawing on the valuable expertise of those most knowledgeable in the field of feline medical care.
  • Bears the full endorsement of the Winn Feline Foundation, a non-profit organization that supports studies about cat health and funds feline research projects worldwide, and is internationally regarded as a major contributor to the health and wellbeing of all cats.
