Our history

Our tradition since 1765: a love of healthy food
and expertise in the production of pet food since 1965

Interquell is a Bavarian family-owned company with roots that date back to 1765. It all began back in the 18th century with a flour mill on the River Singold in Wehringen. In the 1950s, along came a ground-breaking innovation. A new type of technology and appropriate machines could be used to produce cereal flakes – when combined with dried meat, these resulted in the first complete dry food for dogs. Our recipes, ingredients and additives have been refined over the years to take account of the latest scientific findings.
But that is not all: the coveted Happy Cat products have made their way from Wehringen out into the wide world. Happy Cat is now in demand by cat owners, not only in Germany, but also in Europe, most of Eastern Europe and a number of countries in Asia, Africa and South America. Of course, we continue to produce our dry food in our traditional family business in Wehringen, Bavaria.

Our milestones

1765 - The 'old mill '
When it purchased the old mill in Wehringen, the Müller family laid the historical foundation for the company that is now called Interquell. Back then, Nikolaus Müller started to run his flour mill on the River Singold.

Edmund Müller produced the first potato flakes. Due to their easy digestibility and good shelf life, they offered a significant improvement for farmers in feeding their pigs.
