The Feline Patient, Fifth Edition includes 30 additional chapters, along with new clinical pearls providing observations about diseases and procedures gleaned by Dr. Norsworthy over his forty-five years of clinical practice, which are called out in boxes. With clinically oriented images throughout, this edition reorganizes several sections in order to accommodate and better present the massive amount of important information.
• Includes chapters written by a global list of contributors for an international perspective
• Provides new clinical pearls providing useful advice for practice
• Presents an improved layout and page design for ease of navigation
