Objectives To describe the use of a xenotransfusion protocol, the outcome of xenotransfusion in recipient cats and to assess owner memory of the xenotransfusion. Materials and Methods Cats administered xenotransfusions in two hospitals between January 2016 and July 2018 were included. Adherence to xenotransfusion protocol, cause of anaemia, blood type, packed cell volume (PCV), transfusion volume, transfusion reactions, PCV 12 hours after transfusion and survival to discharge were recorded. Owners of surviving cats were questioned to assess if they remembered that a xenotransfusion had been performed. Results Forty‐nine cats underwent the xenotransfusion protocol. The most common causes of anaemia were surgical blood loss (n = 17), immune‐mediated haemolytic anaemia (n = 14) and neoplasia (n = 14). Median PCV before transfusion was 10%. Six cats (12%) had febrile non‐haemolytic transfusion reactions. Median PCV 12 hours after transfusion was 25%. Ten cats (20%) died or were euthanased within 24 hours of xenotransfusion. A delayed haemolytic transfusion reaction occurred in 25 of 39 (64%) cats manifesting as icterus in 15 cats after a median of 1.9 days and haemolytic serum in 19 cats after a median of 2 days. Of the 18 cats alive at 1 week after discharge, 15 (83%) were still alive at a median of 173 days after xenotransfusion. All owners contacted remembered that their cats had received a xenotransfusion. Clinical Significance Xenotransfusion of canine packed red blood cells to cats is possible but haemolysis should be expected between 1 and 6 days after transfusion.

Background Esophageal feeding tubes are commonly used to provide enteral nutrition to cats, but their use is associated with adverse effects. Objectives To evaluate the complications associated with e‐tube placement in cats and to identify factors predisposing to these complications. Animals Cats that had an esophageal feeding tube placed (n = 248). Methods This was a retrospective case review in which clinical records were interrogated across 2 referral centers to identify records of cats that had esophageal tubes placed. Clinical data were collected for signalment, clinical indication, method of placement, time of removal, and any complications. Logistic regression was then employed to assess the odds of an increase in complications, including infection and death. Results For those cats that survived to discharge, tubes were in place for a median of 11 days, ranging from 1 to 93 days. Complications occurred in 35.8% of the cats, with the most common being tube dislodgement (14.5%), followed by stoma site infections (12.1%). Cats receiving glucocorticoids or oncolytic agents (OR = 3.91; 95% CI, 1.14‐13.44) and with discharge at the stoma site (OR = 159.8; CI, 18.9‐1351) were at an increased odds of developing a stoma site infection, whereas those with a lower weight (OR = 1.33; 95% CI, 1.02‐1.75) or (pancreatic [OR = 4.33; 95% CI, 1.02‐18.47], neoplastic [OR = 15.44; 95% CI, 3.67‐65.07], respiratory [OR = 19.66; 95% CI, 2.81‐137.48], urogenital [OR = 5.78; 95% CI, 1.15‐28.99], and infectious diseases [OR = 11.57; 95% CI, 2.27‐58.94]) had an increased odds of death. The duration of time in place and the cat being discharged with the tube in place were not associated with an increased risk of infection or death. Conclusions and clinical importance Owners should be made aware of the potential risks involved and their predisposing factors.

A 5‐year‐old, male, entire labrador was treated for grade III tetanus, developing aspiration pneumonia and undergoing mechanical ventilation. However, 5 days after weaning from mechanical ventilation, the dog developed a new pyrexia. Investigations documented circulating intracellular bacteria, a bacterial peritonitis and a large right jugular thrombus. Blood, peritoneal and urinary cultures yielded a multidrug‐resistant Escherichia coli. The jugular catheter had been in place for 10 days, and the dog had received parenteral nutrition. The pyrexia resolved immediately after catheter removal and there was no echocardiographic evidence of endocarditis. No abdominal source of infection was identified by computed tomography and the septic peritonitis was managed conservatively, including percutaneous placement of an indwelling peritoneal drain for drainage and lavage. The dog was escalated to intravenous gentamicin antibiosis with ongoing supportive care, and discharged with cefovecin, making a full recovery after 20 days in the intensive care unit.
