Question: Diabetes in Pets Part 3

Dr. Schaeberle,

My cat was recently diagnosed with diabetes. I didn’t know it was
possible! What do we do next?

Dear Darlene,

Over the past few weeks I have discussed a diabetes in dogs and cats. Today I will review diabetes in dogs.

Unfortunately, dogs only have the more serious form of diabetes called type I in people. All diabetic dogs require insulin and although weight-loss may lower insulin levels we still must give insulin 2 times daily.

1. Weight control. Because weight loss can be slow and frustrating in many dogs, I will normally start insulin therapy immediately. High fiber diets are recommended for a diabetic dogs to lower insulin levels.

2. Insulin therapy. Until recently, most veterinarians prescribed an insulin made exclusively for dogs. With present shortages of Vetsulin, we are now using human NPH insulin or PZI insulin. As with cats, our goal is to a limit the signs of diabetes such as an increase in drinking and urination and to minimize diseases (such as cataracts and liver disease) that are secondary to diabetes. We begin with a low dose of insulin two times daily to maximize safety and weight loss. Too much insulin can cause hypoglycemia, seizures and even death. Over a period of a few weeks to a month blood sugars are measured to determine the optimal level of insulin.

As mentioned in the initial article control in diabetes mellitus is a both an art and a science. Many dogs and cats can present roadblocks to easy control. But in general, the treatment of diabetes is very rewarding for both the owner and their pets.

Dear Darlene,

Last week I discussed in general terms diabetes in dogs and cats. Today I will focus on diabetes mellitus in cats.

Our general goal of treatment is to decrease of the blood sugar level which will result in less drinking less urination, weight loss and allow for a long quality of life. As with people, we treat diabetes with diet control as well as insulin for most cats.

1. Diet. Addressing pet obesity may eliminate the need for insulin. Recent studies have documented the advantage of a high protein, low carbohydrate diet. Available from your veterinarian, prescription diets can help reach a goal of 1 to 2% weight-loss per week. In addition, canned foods are preferable (they typically have more protein) and scheduling 2 to 3 meals per day (not allowing free choice through the day), can aid in your pet’s weight loss.

2. Insulin therapy. Most veterinarians will select between two available insulins, a new insulin made exclusively for cats (ProZinc) and a human insulin, Lantus. We usually start with a low dose of 1 to 2 units two times daily. Using blood sugar testing as well as a more sophisticated test called a fructosamine, we slowly adjust the insulin to an optimum level over many weeks.

As mentioned last week, treating diabetes in dogs and cats is both an art and science. I have found that it can be challenging to regulate insulin levels if an owner is not compliant to the pets needs. However, with a good teamwork between your veterinarian and the pet owner, most cats will be well controlled with an excellent quality of life and usual life expectancy.

Dear Darlene,

Over the past year there have been many questions involving diabetes in both dogs and cats. I want to make sure I answer most of them, so we will begin a three part series on diabetes mellitus and pets.

Diabetes mellitus is a treatable condition that requires a committed effort by both of veterinarian and client. In the most pets, the treatment is very rewarding and most dogs and cats can live normal life expectancies. The treatment of diabetes is a combination of art and science, due in part to the many factors that affect the diabetic state and the animal’s response. Each animal needs individualized, frequent reassessment, and treatments may be modified based on this response.

In both dogs and cats diabetes is caused by a loss or a dysfunction of the pancreatic cells that produce insulin. The risk factors for dogs and cats include obesity, genetics, and in some cases diseases or drugs. Regardless of the underlying cause, diabetic dogs and cats are hyperglycemic (high blood sugar), which leads to the classic signs of an increase in drinking, urination, and increased appetite and weight loss.

There are many questions the veterinarian must ask him or herself in regards to how to initiate treatment. The variables include a variety of different insulin selections as well as dietary considerations. In many cases the treatment for diabetes in cats differs from that in dogs. Next week I will go over the treatment of diabetes in cats.
