Diabetes mellitus is of increasing concern in both humans and cats. Obese cats are found to be at higher risk of developing diabetes mellitus. Information has not been available on whether glucose concentrations in obese cats differ from those in lean cats throughout the course the course of a day during their regular activities, including consuming food. This study evaluated intra-day and inter-day variations in glucose concentrations in lean and long-term (>5 years) obese cats during a 156-hour period and tested the utility of a continuous glucose monitoring system (CGMS). A CGMS is used frequently in humans with diabetes. The investigators did not detect differences in glucose concentrations between lean and obese cats during the study periods. They also did not detect differences in daily variations in glucose concentrations between lean and obese cats. The results indicate that the CGMS can be useful in evaluating the long term effects of drugs or diet on glucose homeostasis in cats. [VT]
