Court rules pet owners may sue producers of prescription pet foods over price inflation – San Francisco Chronicle

A federal appeals court reinstated a lawsuit Tuesday by dog and cat owners who accused sellers of “prescription pet food” of consumer fraud and price inflation by advertising their products as medically approved.

The products, also known as Rx pet foods, have been widely sold for about 15 years for a variety of conditions and require a prescription from a veterinarian. According to the lawsuit, they can cost two to three times as much as nonprescription pet foods.
