ST. LOUIS (AP) — Nestle Purina PetCare Co. is suing a competitor, alleging that Blue Buffalo Co. Ltd. misleads consumers about the ingredients in its dog and cat foods.

The lawsuit was filed Tuesday in U.S. District Court in St. Louis, where Purina is based. It accuses Wilton, Connecticut-based Blue Buffalo of false advertising, disparagement and unjust enrichment.

Messages seeking comment from Blue Buffalo were not immediately returned.

Blue Buffalo advertises that its pet foods contain natural ingredients and do not contain chicken or poultry byproduct meals. The company also says the pet foods do not contain corn, wheat or soy — potential allergens for some pets.

The suit says testing by an independent lab and funded by Purina showed that several Blue Buffalo products contained "significant" percentages of poultry byproduct meal and corn.
