Domestic cats can significantly impact wildlife, particularly in their role as predators. Studies have shown that cats prey on various wildlife species, including birds, small mammals, reptiles, and amphibians. This predatory behavior can reduce local wildlife populations, especially in areas where native species are already vulnerable or endangered. Additionally, cats can contribute to the spread of diseases to wild animal populations. Cat owners must be aware of these impacts and consider measures like keeping cats indoors to help protect local wildlife ecosystems.
