“The Diet and Feeding Behavior of Feral Cats, Felis Catus at Marion Island”, 1980-04-18 ():
Analyses of prey remains (n = 1,224) and stomach contents (n = 125) of feral domestic cats at Marion Island indicated that these exotic predators mainly feed on nocturnal burrowing petrels (family Procellariidae).
Seasonality in their diet is discussed and predation rate on the various prey species seems to be a factor of availability rather than selection.
An estimate of predation rate based on the energy requirements of the cat population and the caloric content of their most important prey species suggested.
