GPS-based seasonal home ranges of neutered pet cats <em>Felis catus</em> along a habitat gradient

Understanding the habitat-related hunting behavior of house cats (Felis catus) is needed to evaluate their potential predatory effect on areas they actively visit within their home range. As part of a citizen science program, 30 neutered cats from 25 households were equipped by their owners during, on average, 2 consecutive days per month between January and November 2016 with a GPS programmed to acquire fixes at 1 to 5-minute intervals. Nine cats were located in rural environments, 9 in suburban landscapes, and 12 in urban habitats. For 16 of these cats, preys brought home were recorded daily. Using the recursive distribution movement-based kernel density estimator, rural cats had the largest mean home range area (3.5±0.3 ha), followed by suburban (2.1±0.2 ha) and city cats (1.4±0.1 ha). Moreover, suburban cats enlarged their frequently visited areas in April-June, which corresponded to a peak in small bird preys brought home. Our results suggest that a more diversified landscape may drive domestic cats to increase their home range by benefiting from higher numbers of exploitable areas.
