Investigation of pathological haemorrhage in Maine Coon cats

Abstract

Objective Afibrinogenaemic haemorrhage was previously reported in a Maine Coon cat. Two littermates subsequently died from surgical non-haemostasis, suggesting a hereditable coagulopathy.

Methods We prospectively recruited cats which were: a) Maine Coons with pathological haemorrhage (group 1, n=8), b) healthy familial relatives of group 1 (group 2, n=13) and c) healthy Maine Coons unrelated to groups 1 and 2 (group 3, n=12). Coagulation tests: prothrombin time, activated partial thromboplastin time and thrombin clotting time (TCT) were performed on citrated plasma along with quantification of fibrinogen. Routine haematological examination was performed on EDTA-anticoagulated blood collected contemporaneously.

Results Thirty-three blood samples were analysed. Fibrinogen concentrations were significantly reduced in groups 1 (P<0.01) and 2 (P<0.01) compared with group 3. Similarly, TCT was found to be significantly extended in group 1 (P<0.01) and group 2 (P=0.02) with respect to group 3.

Conclusions Dysfibrinogenaemia was identified in clinical cases and their healthy relatives, suggesting that this may represent a hereditary condition of Maine Coon cats. Clinicians should be aware of the increased potential for non-haemostasis in this cat breed and consider assessing clotting function before (elective) surgery.
