The human blood glucose meter for pets to test blood glucose is a certain risk, because humans and cats have very different blood glucose and blood glucose determination standards, non-professional instruments measured blood glucose will have a large deviation from the actual value. The normal blood sugar range for cats is between 80 and 120mg/dL. If the cat's blood sugar exceeds this range, prompt action is needed. If your cat is diabetic, you will need to work with your veterinarian to make sure his or her blood sugar stays within the normal range throughout the day.
