Les hommes ont oublié cette vérité. Mais tu ne dois pas l'oublier, dit le renard. Tu deviens responsable pour toujours de ce que tu as apprivoisé.

Movement and diet of domestic cats on Stewart Island/Rakiura, NZ

Wood, V., Seddon, P. J., Beaven, B., & van Heezik, Y. (2016). Movement and diet of domestic cats on Stewart Island/Rakiura, New Zealand. New Zealand Journal of Ecology, 40(1), 0-0.

Domestic cats (Felis catus) in Halfmoon Bay, Stewart Island/Rakiura, were tracked to assess the
potential for incursions into native forest around the township, and into Rakiura National Park c. 5 km away.
During February and April 2005, 15 and 4 radio-collared cats were tracked, respectively. During a six-month period, cat-owners logged prey brought home by 11 cats. Cats were at home >90% of the time. Of the six cats that left home, movements were small: home range was between 0.05 and 16.6 ha (100% minimum convex polygon). Four cats brought prey home, comprising rats (Rattus spp.; 67% of prey items), and birds (four species, one native; 33%). Cats sampled at Halfmoon Bay were unlikely to enter the national park; however, many locations were within native forest patches, indicating that native birds within Halfmoon Bay were vulnerable to predation. The high proportion of rats caught could have benefits for native species.
