Supplementary Table S1: Australian terrestrial species assessed as more susceptible to predation from savannah than domestic cats.

We assume that any mammal species assessed as at risk of predation by the domestic will be at least as susceptible to predation by the savannah cat (SC). Only those mammal species assessed as more susceptible to predation by savannah cats than by domestic cats are listed here. The full list of all mammal species assessed is provided in Table S1 of Radford et al. 2018 [53]. Female body weight data are mostly from Van Dyck and Strahan 2008 [62], with data on species described since 2008 obtained from the primary sources.

We used evidence based on the relative impacts of and cats in [53] to identify the susceptibility of each mammal species to domestic cat predation alone. For example, if a species was assessed as highly susceptible to predation by cats and foxes in [53], with the impact of foxes rated as being stronger than that of cats (cat < fox), we conservatively rated the susceptibility of that species to cats alone as low. If a species was assessed as being of high or low susceptibility to predation by cats and foxes in [53], with the impact of foxes being equal to that of cats (cat = fox), the susceptibility of that species to cats alone remained unchanged. IUCN : LC = Least Concern, NT = Near Threatened, VU = Vulnerable, EN = Endangered, CR = Critically Endangered.
