WALTHAM Pet Nutrition Research

The WALTHAM Centre for Pet Nutrition is recognised as a leading scientific authority in pet nutrition and wellbeing. Our researchers work across multiple disciplines broadly linked with pet nutrition and health including:

  • Nutrient requirements for various life stages
  • Energy requirements
  • Gastrointestinal health
  • Immune function
  • Skin and coat condition
  • Feeding behaviour
  • Clinical nutrition

With over 600 peer reviewed publications since the 1960s and more than 100 references in the 2006 edition of the National Research Council’s Nutrient Requirements of Cats and Dogs publication, we are committed to publicly sharing key findings with the scientific and pet care communities, providing benefits to pets across the globe.

Cat Eating

WALTHAM has been instrumental in helping to define the essential nutrient requirements of cats and dogs. Key milestones include determining the levels of taurine required in the diet of cats in 1982, helping define the calcium requirements of growing kittens in 1999 and more recently, identifying the safe upper level of vitamin A in the diet of growing puppies.  WALTHAM research has also demonstrated the role of specific nutrients in aspects of health such as skin and coat and the urinary tract.   Delivering the appropriate ranges of all essential nutrients within a balanced daily calorie intake is an additional challenge for pet food manufacturers. There is still so much to learn about nutrition, energy requirements and the factors influencing healthy weight maintenance for dogs and cats from kitten or puppy to the senior pet. WALTHAM continues to invest in research to progress the knowledge within the pet nutrition and health field in order to lead the Mars Petcare vision to create a better world for pets.
