Abstract
The stomach contents of 93 cats from rural and pastoral Western Australia were compared using the
number and biomass of food items, and by calculating an Index of Relative Importance for each food
category. Species of small native mammals (e.g. dasyurids, rodents) and geckos were significantly
(P < 0.03) more prevalent in the diet of pastoral cats, and rural cats consumed greater (P < 0.03) quantities
of introduced rodents and rabbits. Several other groups of native animals (e.g. snakes, skinks, agamids)
were also more prevalent in the stomachs of pastoral cats (P < 0.10). Birds and orthopterans were important
food items to cats from both habitats. There was reasonable dietary overlap (mean = 0.71) between the cats
from both habitats, but the dietary breadth of the pastoral cats (mean = 0.44) was two-fold greater than that
of the rural cats (mean = 0.21). These findings are compared with previous studies, and are discussed with
respect to possible implications for future management strategies for feral cats.
