Finding patterns in cat behaviour would help us to stop feral cats from chewing their way through native bat roosts and bird life. And so a group of New Zealand researchers pored over 36 studies from around the world in an attempt to understand the size of feral cats’ home range—where they hunt, mate, and nurse their young. “Are there similarities between cats?” they asked. Surprising nobody, the answer is no. The study, published in the New Zealand Journal of Ecology, found no discernible patterns to the cats’ behaviour, even when taking into account the effects of season, habitat type, cat size, and competitor animals. One male cat roamed 3232 hectares, its home range the area of Gisborne. The most adventurous female cat roamed 2078 hectares; another stayed within 10 hectares. As any cat owner might tell you, every feline has a different idea of home.
