Most of the previous studies suffered from lacking causality or small sample sizes. To overcome these limitations, we conducted a comprehensive study involving 55 owned domestic cats in a French suburban area where each cat was monitored during one or nine sessions over 5 years and all four seasons. We tracked the cats using GPS technology while controlling for the device used for monitoring, climatic conditions, environmental changes, and their degree of roaming. Using linear mixed-effect models, we found that age and sex significantly predict home range size. Younger cats tend to have larger home ranges and male cats have larger home ranges compared to females. We also found that the device used during the monitoring influenced the size of the home range. Surprisingly, climatic conditions, surrounding environment and degree of roaming had no significant impact. When considering our models, most of the variability in home range size was due to random effects that accounted for the identity of cats which were monitored one or more times. Therefore, a deeper understanding of intrinsic and extrinsic factors influencing home range size in domestic cats is crucial. This includes investigating individual behavior, breed-specific traits, and the role of owner care but also reassessing management solutions for reducing cat roaming and not only focusing on restrictive ones. Identifying these factors will enable the development of more effective management.
