Unlike dogs it is very common for cats to have a mildly elevated blood sugar on screening lab work due to stress, called stress hyperglycemia. In some cats this can become higher then your kitties making it hard to differentiate from diabetes. But, cats with diabetes usually have other symptoms that normal cats do not have like increased thirst and urination, and their blood sugar is typically >250 or higher. Some pre diabetic cats will start out with a lower value so monitoring the blood sugar over time or additional testing can be used to differentiate stress from real high blood sugar if needed. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
