In this study, the changes in serum glucose and fructosamine levels according to the sampling time in cats anaesthetised for castration and ovariohysterectomy were investigated. The study material consisted of 25 cats aged between 6 months and 2 years. Blood samples were collected from the anaesthetised cats (medetomidine, butorphanol, ketamine) before anaesthesia, at the beginning of anaesthesia, before awakening from anaesthesia and after awakening from anaesthesia. Glucose, fructosamine, cholesterol, triglyceride, total protein and albumin levels were measured in the sera obtained. In the statistical comparison made according to the measurement times, it was found that serum glucose level changed significantly. However, no statistically significant difference was found in serum fructosamine levels. It was evaluated that the variation in glucose levels in the perioperative period may be related to anaesthetic agents, and although there was no statistically significant change in fructosamine levels, one of the reasons for the increase in glucose levels observed in the perioperative period was probably operation stress. The results of the study showed that serum glucose measurements are important in perioperative glycaemic control of cats, and serum fructosamine measurements have diagnostic value in the exclusion of possible perioperative hyperglycemia that may develop for different reasons. The stable serum fructosamine level in the perioperative period can be accepted as an indication that it was not affected by the anaesthetic agents used in this study.
