The American pet manufacturer Natura Pet Products has initiated a limited, voluntary recall of certain dry cat and dry ferret food lots produced in its facility in Fremont, Nebraska. Due to a formulation error, these products contain insufficient levels of vitamins and excess minerals. According to the company, there have been no reports of animal health concerns to date, but these lots do not meet established quality standards and should not be consumed by pets, said Natura. Retailers have been contacted and instructed to immediately withdraw these lots from store shelves, stresses Natura Pet Products. Consumers who purchased the product should discontinue feeding the product immediately and discard as normal household waste. Natura said it is taking immediate corrective action as a result of its investigation.
