Who Makes It
Castor & Pollux is a natural and organic pet food brand owned by Merrick Pet Care, which is part of Nestlé Purina PetCare. It is best known for its ORGANIX line, which the company says was the first certified organic dog and cat food to meet all requirements of the USDA National Organic Program, and for its Pristine line. 1, 2
Where It Is Made
When Merrick bought the brand in 2012, it said Castor & Pollux operations would be consolidated at Merrick's facilities in northwest Texas. Operations then moved from Oregon to Amarillo, Texas. 1, 3
History
Brian Connolly and Shelley Gunton founded Castor & Pollux Natural PetWorks in Clackamas, Oregon, in 2000. Merrick Pet Care acquired it in April 2012, and Nestlé Purina PetCare bought Merrick from Swander Pace Capital in 2015. The former castorpolluxpet.com website now redirects to Merrick's site, and review sites report that many Castor & Pollux products appear to have been discontinued, although no formal announcement was found. 1, 3, 4, 5
Worth Knowing
In May 2018, Merrick voluntarily recalled two Castor & Pollux Good Buddy beef dog treats, Prime Patties and Sausage Cuts, because they might contain elevated levels of naturally occurring beef thyroid hormone. The recall did not include any ORGANIX dog food. 6, 3
