Immobilisation and anaesthesia of wild felids may be complex and potentially dangerous events, making it difficult to implement more advanced anaesthetic techniques such as neuraxial anaesthesia. A Eurasian lynx was referred for femur fracture repair after it was seen with lameness of the left pelvic limb sustained in its natural environment. The animal was remotely darted using a combination of ketamine (5 mg/kg) and xylazine (5 mg/kg) intramuscularly. Once immobilised, the lynx was transported to the veterinary hospital in a restraining cage. After induction and endotracheal intubation, pelvic limb radiographs confirmed a closed, comminuted fracture of the left femur that required open reduction and internal stabilisation. A sacrococcygeal epidural was performed before surgery using lidocaine (2 mg/kg) and morphine (0.1 mg/kg) to complement the ketamine–xylazine–isoflurane anaesthesia, which allows a low‐end‐tidal isoflurane concentration. Clinical signs were continuously monitored and remained stable during the entire procedure, with the exception of a temperature that decreased to 35.8°C. No intraoperative analgesic rescues were necessary. Recovery was smooth and uneventful. The lynx showed no signs of motor weakness after surgery or other side effects related to the anaesthetic procedure. The successful management of this surgical case suggests that the described anaesthetic protocol could be recommended in orthopaedic procedures of the pelvic limbs in wild Felidae.

The ovariectomy (OVE) procedure can trigger somatosensory and visceral peritoneal nociception. Sacrococcygeal epidural (ScE) anesthesia may complement or replace systemic analgesia used for feline OVE, reducing opioid consumption and their related undesirable adverse effects and consequently reducing or completely blocking the sympathetic nervous system activation during this procedure. The present study aimed to evaluate the activation of the sympathetic nervous system resulting from adding an ScE injection of bupivacaine 0.25% (0.3 mL kg−1) in feline OVE and identify whether this translates to hemodynamic variables stability. A Parasympathetic Tone Activity (PTA) monitor was applied given that it performs analysis of heart rate variability (HRV) detecting changes in sympathetic and parasympathetic tone, making it a good tool for detecting activation of the sympathetic nervous system during the study. Two groups of animals were evaluated in five perioperative times, namely, the control group (CG) (n = 18) with systemic analgesia alone and the sacrococcygeal epidural group (ScEG) (n = 20) with 0.25% bupivacaine combined with systemic analgesia. Thirty-eight female cats were selected. All animals assigned to CG and ScEG were premedicated with dexmedetomidine (20 μg kg−1 IM) and methadone (0.2 mg kg−1 IM). General anesthesia was induced with propofol IV ad effectum and maintained with isoflurane in 100% oxygen. Heart rate, non-invasive systolic and median blood pressure, respiratory rate, and instantaneous parasympathetic tone activity were recorded. Compared to systemic analgesia alone (CG), sacrococcygeal epidural (ScEG) reduced the rise of common hemodynamic variables but did not prevent sympathetic nervous system activation.

Importance: This case report provides clinical insight into a rare presentation of an air‐gun pellet lodged in the nasal cavity of a cat without visible trauma. It demonstrates the diagnostic challenges and reinforces the value of advanced imaging and surgical planning. Moreover, it highlights the effectiveness of ventral rhinotomy with powered tools as a safe, precise method to access the feline nasal cavity. Case Description: A 5‐year‐old female neutered domestic short‐haired cat presented with intermittent unilateral rhinorrhea and increased respiratory noise since her rescue. Physical examination revealed mucopurulent discharge from the left nasal cavity and inspiratory stertor, with otherwise unremarkable findings. Radiographic imaging revealed a metallic‐density foreign body, resembling an air‐gun pellet, within the left nasal cavity. Rhinoscopy confirmed its presence but did not permit retrieval due to anatomical constraints. A ventral rhinotomy was therefore performed under fluoroscopic guidance via the palatine bone using a high‐speed drill, allowing pellet removal. Conclusion: To the authors′ knowledge, this is the first published report of an air‐gun pellet lodged in the nasal cavity of a cat. This case illustrates the usefulness of ventral rhinotomy and powered instruments for achieving precise bone access in this specific context.

This study aimed to determine the agreement between margin status in feline mammary tumors’ surgery by comparing 3 margin assessment techniques and to determine the predictive value of prognostic clinical and histological parameters for margin status using intraoperative margin assessment techniques. During the intraoperative period, 69 surgical margins from 12 female cats undergoing unilateral radical mastectomy were assessed by imprint cytology (IC) and scrape cytology (SC), both intraoperative cytological techniques. The excised mastectomy specimens were then evaluated postoperatively by histopathology (HP). Cochran’s Q test was used to determine differences in positive margin detection for the three methods. The agreement between the three methods was assessed using the Fleiss kappa coefficient. A binary logistic regression model was used to assess whether clinical and histological prognostic parameters could predict intraoperative margin status. There was no significant difference in positive margins between the three methods ( p = 0.174). The agreement between the three methods was poor (Fleiss kappa = −0.020; 95% CI −0.156 to 0.117). Lymphovascular invasion is a significant predictor of a positive intraoperative margin, with an OD of 18.652 (95% CI = 1.742–199.652). These findings suggest that IC and SC are viable methods for assessing the status of surgical margins during surgery for feline mammary tumors. Intraoperative cytology may be complementary to HP, particularly in cases of lymphovascular invasion.

Oral focal mucinosis is an uncommon disorder primarily reported in people and characterised by excessive hyaluronic acid production in the mucosa. This report describes a novel occurrence of oral focal mucinosis in a 3‐year‐old French Mastiff with brachycephalic obstructive airway syndrome, presenting with severe respiratory distress and mucin deposits in the oral cavity, specifically the soft palate and the epiglottis ventral aspect. This is the first account of oral focal mucinosis at these sites and its association with brachycephalic obstructive airway syndrome in veterinary literature. Patient stabilisation followed by folded flap palatoplasty and mass excision resulted in significant clinical improvement. The presence of mucin on histopathological analysis confirmed the diagnosis of oral focal mucinosis. This case presents new clinical manifestations and anatomical sites not previously reported in oral focal mucinosis. It also raises questions as to whether trauma or chronic inflammation may influence cases of oral focal mucinosis in dogs.
