To investigate the characteristics of the unintentional capture on the nationally endangered Tsushima leopard cat by leg snare traps, admission or dead body recovery records of the past 10 years at the Tsushima Wildlife Conservation Center, Ministry of the Environment were used. Data from automatic cameras for wildcat monitoring were also utilized in the study. 16 cases of wildcat capture by leg snare traps were identified, exceeding the number of traffic accidents in 2022 and 2023. Of these, 14 were adult males. The winter-spring period when wildcats were more likely to be trapped overlapped with the period when wildcats were photographed more frequently in the field. Since there is a relationship between increased wildcat activity during the mating season and the timing of incident of unintentional captures, conservation measures taken during this period would be effective in reducing unintentional captures of wildcats. Trapped wildcats are prone to moderate or severe wounds, and their affected parts and general condition deteriorate after released from the trap, so it is risky to immediately return them to the wild. Therefore, it is essential for trappers to follow the rules for trapping wild animals in order to reduce unintentional captures and increase the survival rate of wildcats that have been caught unintentionally.

　We report a cervical mass that was observed in a captive raccoon (Procyon lotor). On the 71st day, surgical removal was performed. Histopathological examination diagnosed the mass as thyroid adenocarcinoma. Following tumor removal, the animal remained in good condition but died on the 230th postoperative day. Postmortem histopathological examination revealed no metastasis of the thyroid adenocarcinoma; however, verrucous endocarditis was identified, and the cause of death was determined to be heart failure. This is the first report in Japan describing the clinical course of thyroid cancer in a raccoon.

　A Ryukyu long-furred rat with a left femur fracture was operated on using a combined intramedullary pin and cerclage wires technique. The intramedullary pin was removed on day 42 and the rat was released on day 86. This report is the first case of surgery for femur fracture in the Ryukyu long-furred rat since 2006. The number of roadkill in the Ryukyu long-furred rat is increasing and the opportunities for surgery is likely to increase in the future. This report may contribute to the therapy of the Ryukyu long-furred rat.
