The Silent City Hunters: Exploring Shrews through Stray Cats (Felis catus) in Urban Ecosystems in Jordan

Abstract

Objective: This study investigates the predatory behaviours of stray cats (Felis catus) in Amman City, Jordan, from April 2021 to August 2024. Stray cats are significant contributors to wildlife mortality and serve as inadvertent tools for biodiversity monitoring. By analysing prey brought by these cats, the research highlights the interactions and distributions of small mammals in urban settings. The research aims to provide insights into the abundance and distribution of shrew species in urban landscapes and explore the potential role of stray cats as contributors to biodiversity monitoring. Materials and Methods: The study was conducted in Dair Ghbar, a residential area with agricultural patches, using opportunistic documentation of prey items presented by stray cats. Over 41 months, a total of 20 specimens were identified, including Pygmy White-toothed Shrews (Suncus etruscus, 16 specimens), smaller white-toothed Shrews (Crocidura suaveolens, 4 specimens), and house mice (Mus musculus). Fisher’s Exact Test assessed differences in predation rates, with p = 0.081. Results: Temporal trends revealed peak predation in 2021 and 2022, with seasonal patterns indicating higher captures in warmer months. Predation rates showed no significant difference between the two shrew species, but S. etruscus was predominant, highlighting its adaptability to urban habitats. Seasonal variation is likely to correlate with the reproductive and activity cycles of small mammals. Conclusion: This study underscores the dual role of stray cats as ecological disruptors and biodiversity monitors. The predominance of shrews, which are sensitive to habitat fragmentation, underscores the ecological value of urban green spaces. Despite urbanisation, these areas serve as crucial refuges for biodiversity. Stray cats provide costeffective insights into elusive species like shrews but also pose threats to urban biodiversity. Future research should incorporate larger datasets and complementary methods to balance conservation strategies with urban ecological dynamics.
