Mark L. Morris, Jr., DVM, MS, Ph.D., DACVN, is known for his advances in therapeutic and life-stage veterinary nutrition. During his career, Dr. Morris developed more than 130 innovative products by expanding the line of Prescription Diet foods and creating Science Diet to sustain healthy pets.

Dr. Morris was a 1958 graduate of the College of Veterinary Medicine at Cornell University and completed his master’s and doctorate degrees at the University of Wisconsin in 1963. After graduating he began working in the family business, Mark Morris Associates. Within months of moving to Topeka, Kan., Dr. Morris was drafted and served as a Lieutenant in the U. S. Army Veterinary Corps and worked as a laboratory pathology officer from 1958 to1960.

Many of Dr. Morris’ products solved complex nutritional problems, but one of the most notable and revolutionary was Prescription Diet® s/d® Feline. This was a landmark innovation in the world of pet nutrition because it was clinically proven through X-rays to dissolve struvite stones in cats with lower urinary track disease. This dietary solution eliminated the need for surgery in countless cats.
