An extraordinary
idea is born

The history of ZuPreem® started with an idea – an idea that changed the way we look at the role of nutrition in the lives of all animals. The idea was revolutionary and at the same time very simple. Passed down through three generations this idea continues as the mission of the ZuPreem brand today and its guiding force for years to come.

Generations of commitment to animal science

The idea for better animal nutrition started in veterinary medicine in 1928 when Mark L. Morris, DVM, founded the Raritan Animal Hospital, the second small animal hospital in the United States. Dr. Morris discovered that sick dogs and cats could be treated by changing their diets – changes that sometimes eliminated or added nutritional elements to their diets, depending on their condition or disease.

Raritan Animal Hospital in 1928 where the original Hill's prescription diets were formulated. This contribution to animal nutrition eventually led to the development of the ZuPreem line of diets that are available worldwide today.

Prescription Diet®

At the Raritan Animal Hospital, Dr. Morris formulated the beginning of the Prescription Diet® line of products for sick dogs and cats. These products included diets for kidney disease, heart disease and intestinal problems. Dr. Morris passed his commitment to bettering the lives of animals through proper nutrition to his son, Mark L. Morris Jr. DVM, PhD.

Science Diet®

Dr. Mark Morris Jr. continued his father’s work by expanding the Hill’s Prescription Diet® line to include reducing diets, diets to treat urinary tract diseases and later formulating Science Diet® products for the prevention of nutrition-related diseases in healthy dogs and cats. The Science Diet brand of nutrition for canines and felines has become the standard in quality nutritional products worldwide.

ZuPreem® Exotic Animal Diets - Exceptional Diets for Extraordinary Animals®

Just as the original Prescription Diets developed out of a need for better nutrition for dogs and cats, so did the ZuPreem line of products.

We’re glad we picked up the phone 50 years ago, and talked to a zoo director who wanted to explore a different way to feed the animals in his zoo’s collection. Our response launched the ZuPreem brand and forever changed how and what we feed these extraordinary animals.

Building on this heritage, ZuPreem expanded the brand to include nutrition for non-traditional pets, with a focus on caring for each animal and each caregiver with the highest quality, most perfectly formulated nutrition possible.

Today, trusted, top-selling ZuPreem branded products are found in pet retail stores, veterinary clinics, zoos and breeding facilities worldwide.
