Each volume of CONSULTATIONS IN FELINE INTERNAL MEDICINE addresses carefully selected contemporary issues of clinical relevance to the progressive feline practitioner. This new, fourth volume reflects the rising expectations of cat owners by addressing a fresh set of important issues affecting feline health, such as diseases of maturity and prolonged life. It includes cutting-edge chapters on tertiary-care medicine: renal transplantation, hemodialysis, brain tumor management, and molecular diagnosis of genetic disease in purebred cats, for example. At the other end of the spectrum, because overpopulation continues to be a nationwide problem, it contains chapters on population medicine, feral cat management, and shelter medicine.
