Veterinary therapeutic diets often contain undesirable ingredients like corn and by-products
Science Diet is a brand of pet food formulated to meet the needs of healthy pets during various life stages. It is manufactured by Hill's Pet Nutrition, Inc., which also produces a separate range of therapeutic pet foods called Prescription Diet. These are formulated to address specific medical conditions that can develop in pets.
Prescription Diet products are available through a veterinarian or authorised online retailers. However, it is important to note that, legally, you do not need a prescription to purchase a "veterinary prescription diet" or "therapeutic diet". Nevertheless, most veterinarians and pet food stores will not sell these diets without a prescription to avoid conflict with manufacturers.
Veterinary therapeutic diets are often criticised for containing undesirable ingredients like corn and by-products. However, some ingredients, such as corn, are included because they are low in phosphorus, sodium, and potassium, which is important for managing certain medical conditions. For instance, keeping phosphorus levels low is critical for managing kidney disease in cats. Nevertheless, some veterinarians may recommend alternative "healthier" foods that address the underlying cause and nutritional needs of a medical condition.
For instance, a therapeutic diet may be recommended for a pet with kidney disease or osteoarthritis. In such cases, a veterinarian may recommend a therapeutic diet with known kcal/kg density and an exact feeding plan to prevent excess weight gain in at-risk pets. Additionally, therapeutic diets are subject to more stringent quality control measures than over-the-counter diets.
