Are Prescription Diets Really Worth It?

Before you go out and buy your cat some prescription cat food, take a moment to consider whether it is really worth it. To understand what prescription cat food is, it may help for you to learn the basics about the history of this type of diet. The first prescription cat food diet was created in the 1930s by Dr. Mark Morris, Sr. Morris studied veterinary science at Cornell University and he worked with the American Humane Association to create a meat-free diet to help feed dogs during World War II when food rationing was in full swing. This diet was made with rejected eggs, soybeans, unsalable fish, and other ingredients that provide protein as well as cooked cereal grains, vegetables and other ingredients.

After the war ended, many pet food manufacturers started to reincorporate meat into their products, creating higher protein recipes that were more in line with the dietary needs of carnivorous animals like dogs and cats. Morris, however, continued to follow his previous formulations, stating that the move toward all-meat diets – particularly those made with animal by-products – was ridiculous. Using these same principles, Morris went on to develop a number of Prescription Diets (a term which is actually a registered trademark) for the Hills Pet Nutrition Company. The first of these was a formula intended to help dogs reduce their weight – it was formulated in such a way as to keep the dog full without providing much actual nutrition and without causing nutritional deficiencies. One of the key ingredient (and one that is found in many Prescription Diets today) is a combination of pulverize cellulose, also known as sawdust or wood pulp.

If you take the time to examine the ingredients lists for many popular Prescription Diets for cats, you may be surprised to find that many of them include low-quality ingredients like corn gluten meal, wheat flour, and an assortment of by-products and by-product meals. In fact, it is not uncommon for prescription cat foods from Hill’s and Royal Canin to list four or five carbohydrate sources within the first 10 ingredients on the list, often before the first protein source is even mentioned. This is not to say that all prescription diets are low in quality, but you do need to be very careful when shopping for veterinary formulas because there are a low of products out there that are no different from the average low-quality cat food.

Alternatives to Prescription Cat Food Diets

Because there is a great deal of controversy regarding the quality and efficacy of prescription cat food, you may be wondering if there is a better alternative. Depending on what condition your cat is currently suffering from, there very well could be! For example, if your cat suffers from skin allergies or food sensitivities, his problems could be solved by switching to a limited ingredient diet (LID). These diets are made with a selective number of ingredients, often choosing novel protein and carbohydrate sources to reduce the chances for an allergic reaction. Many prescription cat food diet that are designed for cats with food sensitivities are made with hydrolyzed animal proteins which are chemically treated and exposed to extreme heat in order to change the make-up of the protein so it doesn’t cause a reaction. All that really needs to happen to prevent your cat from having an allergic reaction, however, is to remove the offending ingredient from his diet – why feed him protein that has been chemically treated if all you really needed to do was switch to a different protein?

In a similar way, many prescription cat food diets that are designed to help cats lose weight are made with ingredients that have been altered to reduce their calorie content. In many cases, these low-calorie ingredients are also very low in nutritional value on the whole – why would you want to choose that for your cat? If you look at weight management formulas from high-quality cat food brands like Natural Balance or Blue Buffalo you will find that these formulas are still rich in nutrients. Rather than bulking up their products with low-quality fillers that will keep your cat full without providing much nutrition, these formulas focus on maintaining your cat’s lean muscle mass while reducing his fat intake to cut calories. There are plenty of animal proteins that are naturally lean and low in calories – chicken, turkey, and fish are some great examples. And fresh fruits and vegetables can provide dietary fiber and other key nutrients without significantly impacting the calorie content of the food.

When it comes to actual medical problems such as bladder stones or kidney issues, feeding your cat an actual veterinary diet might make a little more sense. Bladder stones in cats are caused by a buildup of certain minerals in the urine such as phosphate, magnesium, and ammonium – the pH of your cat’s body can also impact the development of these stones. While some dietary modifications may be needed to help dissolve existing stones, many cat owners find that increased water consumption makes the biggest difference in preventing stones from forming in the future.

Kidney problems like renal failure are also very common in cats and many pet owners try to treat the disease by switching their cat to a low-protein prescription cat food diet. If you take a look at recent research, however, you will see that some types of renal failure in cats are not affected by protein or calorie intake at all. In fact, it is more beneficial to provide your cat with a high-protein, balanced diet that will support his total body health and wellness, helping him to maintain healthy blood pressure and healthy blood volume. Furthermore, protein is actually a requirement for the repair of kidney cells – the kidney cannot recover if your cat doesn’t get enough protein.
