The Feline Patient, First Edition, circa 1998, was conceived by four individuals who wanted to produce a practical book to guide veterinarians who treat cats, whether in feline-only practice or in mixed-animal practice. Their goal was to produce a book that emphasized diagnosis, treatment, and prognosis, and did so in a rapid retrieval approach. The Founding Authors, as we designated ourselves, identified the important diseases of the cat and authored every chapter. With each subsequent edition, more authors with specialized expertise were added as the list of diseases expanded. This is to recognize the Founding Authors for their foresight and determination to achieve the original goals of producing a quick-reference book for the busy practitioner.
