Daily GPS movement and activity of free-roaming male cats before and after gonadectomy — a longitudinal within-individual study (Barlovento, La Palma)

This dataset contains daily GPS movement and accelerometer-based activity data for twelve free-roaming cats from a managed (trap–neuter–return) community-cat colony in Barlovento, northern La Palma, Canary Islands, Spain (UNESCO Biosphere Reserve). It supports a longitudinal, within-individual study of how gonadectomy affects ranging in male cats: three intact males (two adults and one juvenile) were tracked before and after neutering, while nine already-neutered cats served as a contemporaneous control band. Cats were fitted with Tractive GPS-and-accelerometer collars (median fix interval ≈ 5 min). Monitoring was intermittent, comprising a 15-day pre-surgical baseline (12–26 July 2025) and three post-surgical windows (6 Aug–8 Sep 2025; 20 Dec 2025–9 Jan 2026; 25 Mar–3 Apr 2026), giving 80 monitored days per cat (960 daily records). The package includes: the daily data in tidy long format (CSV) and documented Excel; per-animal metadata; the raw GPS tracks (KML/GPX) used for home-range estimation, renamed to anonymised codes; derived outputs (linear mixed-model results, home-range areas); and the analysis scripts (Python and R) that reproduce the published results. Individuals are identified by anonymised codes; all values are real, device-recorded measurements. Ethical approval: OEBA_ULPGC_35/2023 (University of Las Palmas de Gran Canaria).
