Karl, B. J., & Best, H. A. (1982). Feral cats on Stewart Island; their foods, and their effects on kakapo. New Zealand journal of zoology, 9(2), 287-293.
The foods of feral house cats (
Felis catus) on Stewart Island were determined by examining 229 scats collected during surveys of the distribution and numbers of kakapo (
Strigops habroptilus), an endangered ground-parrot species. Rats occurred in 93% of the scats, birds in 44. 1%, wetas (large orthopterans) in 26.2%, and lizards in 24.0%. Twelve (70.6%) of the 17 species of birdswere native. Kakapo remains were found in 6 (5.1%) of the 118 scats collected from areas where kakapo have been recorded.
