Abstract Home range (HR) is a key indicator of animal spatial ecology. HR size, shape, location and habitat composition reflect both species' ecological requirements and their responses to anthropogenic stressors. Felidae , a charismatic taxon, faces escalating threats mainly due to habitat degradation and human–wildlife conflict. Understanding the ecological and anthropogenic drivers of HR size variation is therefore critical for their conservation. To address this gap and explore these factors at a global scale for the entire taxon, we used the HomeRange database—a global database with HR values across 960 different mammal species—complemented with about 20% additional records, to compile 1137 individual HR size estimates from 29 out of 40 recognized wild felid species. We applied generalized linear mixed models to assess the influence of intrinsic, methodological, ecological and anthropogenic factors on space use. HR size was shaped by multiple drivers. It increased with body mass (0.94 ± 0.16; p < 10 −8 ) and was larger in males than in females (0.51 ± 0.07; p < 10 −13 ), consistent with higher energy demands and sex‐specific reproductive strategies. HR size decreased with increasing productivity (−0.37 ± 0.07; p < 10 −7 ) and felid richness (−0.24 ± 0.10; p = 0.02), suggesting reduced spatial requirements in resource‐rich areas and under interspecific competition. HR size also decreased with increasing croplands (HR: −0.50 ± 0.14; p < 10 −3 ) and pastures (HR: −0.16 ± 0.07; p = 0.02)—both human footprint proxies—which may reflect multiple causes such as anthropogenic food sources, habitat loss or movement restriction from infrastructures associated with agriculture. Our results reinforce the role of well‐known established HR size's predictors such as body mass, sex and primary productivity while highlighting the impact of less frequently investigated factors (i.e. felid richness and agricultural land‐use). Our findings emphasize the importance of incorporating a broad range of biological, environmental and methodological predictors when studying space use across a taxonomic group. Our approach provides novel insights into habitat requirements and the effects of anthropogenic pressures, which can ultimately lead to improved conservation strategies for felids.
