DIA-IONX is usually given along with insulin. If you can't afford insulin you could try a conservative approach with diet or maybe you could use insulin for a short while to get things under control. Have you tried Costco or Sam's Club for insulin? You might be able to fill prescriptions without a membership. I would suggest you try DIA-IONX because it helps to control the symptoms of diabetes and it's therapeutic mineral base helps activate the enzyme systems in the body that help with healing. Some owners have told us it has helped stabilize the blood glucose levels. The dose I start with in cats is 10 drops twice per day on the breakfast and supper canned food. In addition I like to give probiotics and Omega 3,6,9 daily. DIA-IONX will help the body better utilize the other supplements for a synergistic response. In addition make sure that you offer sufficient water free of chlorine and free of fluoride.
A regular exercise schedule is also helpful in moving glucose from the blood and into the muscles which will reduce the blood glucose. Your veterinarian will probably recommend a low carbohydrate diet that is high in fiber. It is important that you avoid giving dry food. Canned food would be better because dry food puts more stress on the pancreas. If a diabetic cat has been able to stop needing insulin injections while on a canned food diet only, they became diabetic again when given dry food. If your cat does not like prescription canned food you could offer a low carbohydrate one. Low carbohydrate canned foods that are nonprescription include Friskies Classic Pate Salmon, Fancy Feast - Savory Salmon Feast, Turkey and Giblets Feast, and White Meat Chicken Florentine. These are 2% or lower in carbohydrates.
Be sure to monitor your cat's blood sugar so that you will know if it is appropriate to change anything.
