Abstract
A feral cat population was substantially reduced by poisoning at a semi-arid
site in Western Australia. The control programme was designed to protect two
species of endangered native mammals that had recently been reintroduced to
the site. Feral cats were poisoned with carcasses of laboratory mice, each
impregnated with 4.5 mg of sodium monofluoroacetate (1080). Baits were placed
at 100-m intervals along the track system each night for four consecutive
nights. Kill rates were assessed by monitoring survival of radio- collared
cats and by spotlight counts of cats before and after baiting. All
radio-collared cats were killed and there was a 74% reduction in
spotlight counts of cats after baiting. Bait removal varied with the abundance
of rabbits, the primary prey item for cats in this area. Effectiveness of
control operations against feral cats is maximised by baiting at times of low
prey abundance. Monitoring the changing abundance of the primary prey species
provides important information for timing control operations against feral
cats.
