Abstract: ABSTRACT: Feline obesity has become an increasingly common problem worldwide over the past decade. Excess weight in cats may predispose them to a range of conditions such as insulin resistance, type 2 diabetes mellitus, and hepatic lipidosis. However, few studies have conducted clinical-laboratory profiles of overweight and obese cats. Therefore, the aim of this study was to describe and correlate clinical and laboratory alterations in overweight and obese cats, comparing them with lean cats. Fifty-three cats were evaluated and divided into obese (OB), overweight (SP), and control (CT) groups. After a clinical assessment, the clinically selected cats underwent morphometric measurements and hematological and biochemical tests; their owners were also instructed to complete a questionnaire. Our primary findings included an increase in mean corpuscular volume and total proteins, a decrease in red blood cell count, and an increase in circulating concentrations of total cholesterol, triglycerides, and urea in the OB group; the SP group exhibited an increase only in total cholesterol and urea. Furthermore, the OB and SP groups exhibited a higher frequency of ad libitum feeding, were more likely to receive premium food, and generally had lower activity levels. We concluded that being overweight or obese altered the cats’ hematological and biochemical parameters. Moreover, factors related to the feeding and environmental management of cats may predict an increased risk of being overweight.
