About CarbCalc

Does your cat have diabetes? Have you resolved yourself to having to give regular insulin shots for the rest of your kitty's life? Do you feel that there is no hope left?

Have you looked into the Tight Regulation Protocol?

Unfortunately, because of the diet that many cats eat, Feline Diabetes has become all too common. At Diabetic Cat Help, we practice a leading edge treatment protocol called Tight Regulation (TR) that has brought thousands of diabetic cats back to far better health, and a great many of those cats into remission. Developed by Dr. Elizabeth Hodgkins, DVM, Tight Regulation for cats is similar to the way that humans treat their own diabetes.

One of the cornerstones of the Tight Regulation Protocol is that cats should be fed only high quality, low carbohydrate, canned foods. This app provides an easy method for calculating the carbohydrate content of cat food.

 Enter the Protein, Fat, Fiber, Moisture, and Ash values from the back of any can of cat food, and Carbohydrate value will be displayed. The goal of CarbCalc is to make the selection of cat food a simple and straightforward process.


Enter the required values from the back of any can of cat food. If Ash is missing from the label, use a value of 2.9. Once all values are entered, the results will be automatically calculated. Changing values will cause the results to be recalculated.

There is an option available to have the results highlighted in Green, Yellow or Red, to make food selection easy. Green indicates a great food for your cat. Yellow indicates that the food is ok, though there are better choices. Never feed your cat any food that results in the color Red, as those foods are too high in Carbohydrates.

There is an option available to list information about whether or not a calculated food is a good food to feed a cat.

Tap the clear button clear all values and start over.

Store a food in the handy library by simply tapping the add button. Foods lists can be accessed at any time, printed, or emailed. And foods in the library can be edited at any time.

The output screen allows printing, emailing, and copying of food data. Filters can be set to limit what is printed. Select only the information needed.

Disclaimer: This app is not a cure for Feline Diabetes. Once a cat is diabetic, it'll always be diabetic. This is one tool that can be used to assist in getting your cat back to better health, and in some cases, into remission.

If you find this app to be useful, please consider leaving a review. There is also a link in the settings menu for donating to me, should you desire to do so. Many hours of work goes into development and maintenance on this app. Anything is appreciated.

Thank you.
