Rx Diets

I am a veterinarian. Do the Rx diets follow AAFCO on an as fed basis or as formulated basis (meaning tested using a feeding trial).

The Rx diets do not attempt to target AAFCO levels but are rather nutrigenomically designed to address organ systems. However, Wysong Rx diets do meet (actually exceed) the nutrient requirements set by AAFCO for maintenance for cats and dogs. This is on an as fed basis.

Myth of the 100% Complete Processed Pet Food:


A literature packet has also been sent as you have requested. We included some product samples as well.

I have a cat with FLUTD and my vet suggested Wysong Uretic since I was very unhappy with the ingredients in the prescription food I was giving him. The ingredients in your food are excellent, but I am curious as to why it has such a high carb content at 32%?

All dry kibble foods (with the exception of the Wysong Epigen™ products) must use a starch source to bind the kibble. This necessity creates the carbohydrate content, and Uretic has an average carbohydrate content compared to other foods. It is not considered a high percentage. In fact, Wysong diets boost a lower glycemic index than other foods on the market. For instance, Uretic™ is lower in carbohydrate content than some other popular diets for urinary health, such as Hill's C/D (41%).

Also keep in mind that Uretic™ is just one diet option that Wysong offers for cats prone to urinary problems. For the best health, Wysong recommends feeding a variety of foods.

A good starting point for cats with urinary problems is Uretic™ and Epigen™ (starch free™) dry, supplemented with Archetype™ and the Au Jus Canned Diets™ or fresh meat. We also have a supplement, Biotic pH-™ for those cats requiring additional help maintaining a more acidic urine pH. Biotic pH-™ also enhances digestion and absorption by supplying probiotics (good bacteria) and enzymes. Also, consider supplementing with Wysong E.F.A.™ (essential fatty acids, which are anti-inflammatory).

The Wysong Rx diet for struvite crystals is Urinary™. It would be recommended to supplement the diets mentioned above with the Rx diet, either as a top dressing or a snack (see intermittent and varied article).

You can order Rx diets directly from Wysong as long as we have a prescription on file from your vet stating the name of the diet, your name, the pet's name and the number of refills. You can fax that information to us at 989-631-9280. If your veterinarian wishes, they can also order the Rx diet for you.
