Mars Petcare is celebrating 30 years of manufacturing at its Birstall site.
The factory has been making pet care and treats since 1987.
Over the past 30 years, the Birstall site has produced an astonishing 40,000 tonnes of the UK’s best-loved pet care and treats products.
The Yorkshire factory is regarded as the birthplace of Pedigree® Dentastix®, which has a unique X shape and, when fed daily, its special texture is scientifically proven to help reduce the build-up of tartar by up to 80%.
Birstall has produced four billion Dentastix® since it launched in 2002 (enough to reach to and around the moon).
Sarah Sordy, operations manager at the Birstall plant, said: “Mars Petcare Associates at Birstall have been celebrating our 30th birthday all year.
“We’ve eaten an 1980s style lunch together, taken part in a sports day, volunteered in local schools and eaten lots of retro themed birthday cake.
“The reason we’re celebrating is to say thank you to all our employees who’ve worked so hard over the years to make Birstall a leader in pet care manufacturing.”
