Study examines canine plasma xenotransfusion in 14 cats

A new multicenter retrospective study in the Journal of Veterinary Emergency and Critical Care reviewed 14 cats that received canine plasma xenotransfusions between 2022 and 2024, adding early evidence for a practice sometimes used when feline plasma is not available. According to the study abstract, the cases were evaluated for indications, protocols, transfusion reactions, and outcomes, and the authors concluded that canine plasma may be a life-saving option for feline coagulopathies and colloidal support, while emphasizing that its safety profile still needs further investigation. The paper appeared in Wiley’s journal feed in late April 2026. (vetlit.org)

Why it matters: For emergency and critical care teams, the report speaks to a familiar real-world problem: feline plasma can be hard to source quickly, especially after hours or in smaller hospitals. Prior literature has focused much more on canine-to-feline red cell xenotransfusion, where short-term benefit is possible but delayed hemolysis and serious reactions limit repeat use. By contrast, published evidence on canine plasma products in cats has been sparse, making this 14-case series a notable addition for clinicians weighing rescue options in coagulopathic or critically ill cats when species-matched products are unavailable. Reviews and related reports also underscore the broader transfusion-medicine context: cats often face blood-product access constraints, and other canine-derived products, including serum albumin and lyophilized platelets, have been explored in small feline case series and reports.

What to watch: Watch for the full paper, any conference discussion or commentary from transfusion specialists, and whether larger prospective studies help define when canine plasma is acceptable, how to monitor reactions, and which cats are the best candidates. (vetlit.org)
