Petcare – Science | Mars, Incorporated


In Leicestershire, England, we have a fundamental petcare research center, the WALTHAM Centre for Pet Nutrition, that is recognized as one of the world’s leading scientific authorities in the field of pet nutrition and wellbeing.

Our researchers work across multiple disciplines that are linked to pet nutrition and health. Such disciplines include nutrient requirements for different pet life stages and lifestyles, gastrointestinal health, energy requirements, immune function, skin and coat condition, oral health, feeding behavior, and clinical nutrition.

Guided by Mars’ Principle of Mutuality, WALTHAM scientists share their leading research with the scientific community to help make a Better World for Pets around the world. We have published more than 600 peer-reviewed publications within the area of companion-animal nutrition since the 1960s and also have presented our research findings at esteemed conferences and events.



Along with other leading institutions, WALTHAM conducts research about the relationship between humans and companion animals and the positive and lasting benefits pets can have on health.

Our work in this field goes back 40 years and has explored the role of pets in healthy childhood development. It supports the idea that human-animal interaction has clinical potential in supplementing treatment of obesity, autism, hypertension and post-traumatic stress disorder in children and adults.
