Although your Bengal has been diagnosed with diabetes, it does not mean that he will have to have insulin injections on a regular basis. In fact, some diabetic cats tend to do well with their blood sugar or glucose levels by taking an oral medication. Generally, cats that are diagnosed in the early stages of diabetes will do well on an oral medication along with a special diet, weight loss, and exercise. Commonly used medications may include Glipizide. Although not specifically designed for cats, this medication is often prescribed. Side effects are rare, but may include vomiting or loss of appetite. Always notify your vet if your cat has any side effects or reactions to a medication. Your vet will need to monitor your cat’s liver enzymes while on this medication as well. It may take six weeks for your cat’s blood sugar levels to improve. Talk with your veterinary clinic Diamond Bar, CA for more details.
