About us

We have been advancing research into the health of pets for over 50 years, and now we are leading breakthrough science in preventive health.

Waltham is the science centre for Mars Petcare. Our research teams work across multiple disciplines such as nutrient requirements for pets, the dog and cat microbiome, biomarkers of health and disease, and feeding behavior. We also support science in partnership with organisations around the world to understand how our relationship with pets can help both pets and their owners to live healthy, happy lives together. 

At Mars Petcare, we are committed to our Purpose: A BETTER WORLD FOR PETS, and the knowledge generated at Waltham is vital in bringing this vision to life. We take pride in sharing our key findings with the scientific community, enabling pets around the world to benefit from our work. 

Since our first scientific paper over 50 years ago, we have shared our expertise through over 1700 publications, including more than 600 peer-reviewed journal articles. In addition, our scientists collaborate with some of the world’s most renowned veterinary and nutrition scientists.  We also share our scientific findings at conferences and events around the globe, including our open forum, the WALTHAM International Nutritional Sciences Symposium.
