Warfarin and the Grey Squirrel

Coagulation parameters of captive black-tailed prairie dogs (Cynomys ludovicianus)

“…This difference in measurements can be a result of an undetermined subclinical disease in the tested animals in this study or due to difference in the testing methodology between the two studies. The PT in prairie dogs in this study (median 8.4 s and mean 8.6 s) is lower when compared to that described in gray squirrels (Sciurus carolinensis) (mean 13.83±3.63 s) (Chambers and Chambers 1983). The mean PT values reported in this study were also lower when compared to those reported for hamsters, which were 9 s (Valdivia et al 1993), 9.9 s (males) and 9.3 s (females) (Wesche 2009), and 10.3-10.7 s (Suckow et al 2011).…”

“…Almost no published data exists in regard to coagulation parameters in exotic rodents, and limited data can be found for more common laboratory species such as rats, mice, and hamsters (Valdivia et al 1993;Peters et al 2003;Siller-Matula et al 2008). Prothrombin time was reported in squirrels and fibrinogen in prairie dogs, but a systematic review of the literature revealed that other coagulation parameters have not yet been determined in any of the other members of the Sciuridae family (Chambers and Chambers 1983;Tell 1995).…”
