Objectives Bite wounds are a common cause of trauma in cats; nevertheless, large-scale studies of this trauma in cats are lacking. The aims of the present study were to characterise the clinical and clinicopathological findings in these cats, to assess the association of these variables and therapeutic measures with survival, and to assess the association between the animal trauma triage (ATT) score and severity of injuries score (SS) at presentation with survival. Methods The medical records of cats presented to a veterinary teaching hospital and two large referral clinics were reviewed retrospectively. Results The study included 72 cats diagnosed with canine bite wounds (with the dog attacks having been witnessed). Seventy-one percent of cats suffered multiple injuries, and there was a significant association between the number of injured body areas and survival, and between severity of injury and survival ( P = 0.02 and P = 0.012, respectively). The median ATT scores and SSs for non-survivors were significantly higher compared with survivors ( P <0.0001). There was a strong and significant correlation between ATT scores and SSs ( r = 0.704, P <0.0001). Total protein and albumin were significantly lower and alanine aminotransferase significantly higher in non-survivors compared with survivors ( P ⩽0.032). Fifty percent of cats were treated conservatively, 32% by local surgical debridement and 18% of cats required an exploratory procedure. Cats undergoing more aggressive treatments were significantly less likely to survive ( P = 0.029). Fifty-seven cats (79%) survived to discharge. Conclusions and relevance Cats sustaining canine bite wounds have a good overall prognosis for survival to discharge. High ATT score, high SS, multiple body area injuries, penetrating injuries, radiographic evidence of vertebral body fractures and body wall abnormalities, as well as hypoproteinaemia and elevated alanine aminotransferase, are negative predictors of survival.

Objective: To describe acute mesenteric infarction due to suspected Spirocerca lupi aberrant migration in 5 dogs. Case Series Summary:All dogs were large breed, none of which exhibited typical clinical signs associated with spirocercosis. All dogs were eventually diagnosed with septic peritonitis. On exploratory laparotomy, thickening of the jejunal arteries, surrounding mesojejunum, and segmental necrosis were identified. Similar thickening and hematoma formation were found in other regions of the mesentery. In 4 of the cases, the necrotic segment was located in the distal jejunum.Histology revealed thrombotic mesenteric vessels with intralesional S. lupi nematode larvae.Resection and anastomosis of the necrosed section was performed and all but 1 dog survived and were discharged within 1-6 days. New or Unique InformationProvided: Spirocerca lupi is a potential cause of mesenteric infarction in endemic areas when no other obvious etiology is identified.

Case series summary Tooth aspiration is a rare occurrence in human medicine, and even more so in veterinary medicine. This report describes two cats that aspirated a tooth (one canine tooth and one premolar tooth) following maxillofacial trauma. One cat presented with dyspnoea, while the other showed no respiratory clinical signs. In both cases diagnosis was reached by obtaining routine thoracic radiographs, and successful retrieval of the teeth was achieved by bronchoscopy. Both cats recovered uneventfully. Relevance and novel information To our knowledge, this is the first report in the veterinary literature of tooth aspiration into the tracheobronchial tree following maxillofacial trauma. The scope of this case series is to raise awareness that tooth aspiration can occur following maxillofacial trauma and has the potential for serious complications if not diagnosed and treated promptly. Therefore, an oral examination must be performed in every maxillofacial trauma patient and missing teeth should be accounted for, even when respiratory clinical signs are not detected.
