Data and code from: Personality matters: Owner-€ascribed personality predicts range size tendencies and predation behavior in domestic cats

Free-ranging domestic cats (Felis catus) are recognized as invasive and efficient predators on islands, although their impact on continental wildlife remains poorly understood. Predation behavior and space use are key indicators for estimating the influence of these felines on prey populations through direct killings and sublethal effects (landscape of fear). Previous work highlighted – and debated – the importance of biological (sex, age) and environmental (habitat type) factors as well as owner-related habits (feeding, play, hygiene) in shaping hunting and roaming behaviors. However, the influence of individual behavioral characteristics, known as personality, remains largely unexplored. In this study conducted in a suburban area south of Paris, we monitored 23 domestic cats using combined GPS and animal-borne camera devices (or “kittycams”) between March and May 2025. Cat predation behavior was analyzed using a detailed ethogram, and space use was studied through two parameters: core..., , # Data and code from: Personality matters: Owner-€ascribed personality predicts range size tendencies and predation behavior in domestic cats

## Description of the data and file structure

Data were collected to investigate how personality traits influence space use and predation behavior in free-ranging domestic cats (*Felis catus*). Twenty-three cats in a suburban area south of Paris were monitored between March and May 2025 using GPS collars and animal-borne cameras (“kittycams”). Personality scores were obtained from owner questionnaires. The dataset includes anonymized personality scores, home range estimates (aKDEc50 and aKDEc95) calculated from GPS tracks, detailed behavioral data extracted from videos using BORIS software, and R scripts used for data processing and analysis. These data can be used to study links between personality, spatial behavior, and hunting tendencies in domestic cats.
