The habitat use (Gehring & Swihart, ; Saito & Koike, ) and foraging behavior (Mirmovitch, ; Contesse et al ., ) of these two species allow them to establish urban populations (Bateman & Fleming, ), as they make use of a wide range of wild and anthropogenic resources through fragmented urban landscapes (Meckstroth, Miles & Chandra, ; Krauze‐Gryz, Żmihorski & Gryz, ).…”

“…The diet of generalist predators such as foxes and cats depends on prey abundance that may vary temporally and spatially (Paltridge, 2002;Krauze-Gryz et al, 2017). Birds and small rodents are usually found in fox and cat diets within urban and suburban habitats (Meckstroth et al, 2007;Krauze-Gryz et al, 2017). The diet of urban or suburban foxes and cats is also characterized by the use of anthropogenic refuse as a food resource (Mirmovitch, 1995;Contesse et al, 2004).…”

Trophic patterns and home‐range size of two generalist urban carnivores: a review

Foxes and cats are the most abundant medium‐sized urban carnivores. To date, however, there has been a lack of effort to synthesize data on the spatial and trophic resources used by these two carnivores, despite the importance of this information for assessing their similarity and roles in urban food webs. In this paper, we first synthesize all available information on the trophic patterns and home‐range size of these two predators based on a total of 91 studies. Second, we conduct statistical analyses to test the influence of environmental and biological variables such as regional differences, habitat characteristics, age, and sexual status on their home‐range size and diet patterns within urban habitats, and then evaluate the methods used to investigate these components. Our findings highlight the lack of studies that simultaneously monitor the diet and home‐range size of both predators within urban habitats. To the best of our knowledge, this is the first study to compare fox and cat home‐range size and diet. Foxes exhibited larger ranges than cats, while intact cats showed larger home ranges than desexed cats. Diet diversity obtained for both predators confirmed their trophic plasticity within urban habitats. Both predators consumed fewer mammals and invertebrates in highly disturbed habitats compared to medium ones. We also found that the procedure of data acquisition significantly influenced fox and cat home‐range sizes. In terms of diet, the type of recovered samples had a significant effect on the diet composition of both predators. To improve our understanding of the relative impact of these two urban carnivores on urban wildlife, we recommend simultaneously studying both species in future studies. Moreover, methodological standards for both diet and home‐range size studies are needed to allow comparisons.

Pet cat personality linked to owner‐reported predation frequency

The domestic cat, Felis catus, is one of the most popular and widespread domestic animals. Because domestic cats can reach high population densities and retain at least some tendency to hunt, their overall impact on wildlife can be severe. Domestic cats have highly variable predation rates depending on the availability of prey in their environment, their owners' practices, and individual cat characteristics. Among these characteristics, cat personality has recently been hypothesized to be an important factor contributing to variations in the hunting activity of cats. In this study, we surveyed 2508 cat owners living in France about their cats' personalities, using the Feline Five personality framework, and the frequency with which cats bring home prey. Personality traits were analyzed using factor analysis and related to predation frequency using cumulative logit models. For both birds and small mammals, cats with high levels of extraversion or low levels of neuroticism had significantly higher frequencies of prey return. Owners whose cats had low levels of agreeableness or high levels of dominance reported a significantly lower frequency of bird return.Personality differences therefore seem to contribute to the high variability in predation rates among domestic cats. We also found that the owner-reported prey return frequencies were significantly higher for cats spending more time outdoors, for nonpedigree cats, and for owners living in rural or suburban areas as opposed to urban areas. By contrast, we did not detect an effect of cat sex or age on their reported prey return rates.

Free‐ranging domestic cats Felis catus, from owned pets to feral cats, impact biodiversity through predation, fear effects, competition, disease and hybridization. Scientific knowledge regarding these impacts has recently increased, making it timely to assess the role of nature conservation legislation in this connection. We do so with particular regard to the obligations of governments around the world under international wildlife law. First, we provide an overview of current knowledge, based on a literature review, concerning the ways in which domestic cats impact wildlife; the resulting effects on native species’ populations and ecosystems; and available strategies for addressing these issues. In light of this knowledge, using standard legal research methodology, we then identify and interpret relevant legal instruments, with a particular focus on international wildlife treaties. Lastly, we identify and assess factors that may influence the implementation of relevant obligations. The outcomes of this analysis indicate that numerous legal obligations of relevance to free‐ranging domestic cats already apply under global treaties such as the Convention on Biological Diversity, Convention on Migratory Species and World Heritage Convention, and a range of regional legal instruments for biodiversity conservation. Of particular significance are obligations concerning (a) invasive alien species; (b) protected areas and (c) protected species. Many national authorities around the world are currently required, under international law, to adopt and implement policies aimed at preventing, reducing or eliminating the biodiversity impacts of free‐ranging domestic cats, in particular by (a) removing feral and other unowned cats from the landscape to the greatest extent possible and (b) restricting the outdoor access of owned cats. Factors that can influence or impair the application of these obligations include considerations of feasibility, scientific uncertainty, the interests of cat owners and the (perceived) interests of domestic cats themselves. Even if such factors may to some extent explain why many authorities have hitherto failed to take effective action to address the threats posed by free‐ranging domestic cats, from a legal perspective these factors provide little ground for justifying non‐compliance with international wildlife law.
