U.S. Food and Drug Administration released a Compliance Policy Guide (CPG) that explains the criteria FDA will consider when determining whether to take enforcement action regarding dog and cat food diets intended to treat a disease.
Pet food diets labeled with therapeutic claims are specially formulated to address specific diseases (for example, urinary tract disease in cats). In the past, these diets were sold through and used under the direction of licensed veterinarians. However, FDA has observed an increase in marketing of these diets directly to pet owners over the internet and in retail stores. This shift toward direct marketing, without veterinary direction or involvement, concerns FDA because these diets are formulated for specific health needs and may not be suitable for all pets.
In the interest of animal safety, dog and cat food diets labeled with therapeutic claims (e.g., renal failure, diabetes) should be available only through licensed veterinarians or through retailers and internet sellers under the direction of a veterinarian. In addition, comprehensive labeling information and other manufacturer communications for these diets should be made available only through licensed veterinarians.
