Cute Cat

Cats are a cosmopolitan species and are found across much of the world. They are extremely adaptable and are now present on all continents except Antarctica, and on 118 of the 131 main groups of islands – even on sub-Antarctic islands such as the Kerguelen Islands. Feral cats can live in forests, grasslands, tundra, coastal areas, agricultural land, scrublands, urban areas and wetlands. Their habitats even include small oceanic islands with no human inhabitants. This ability to thrive in almost any terrestrial habitat has led to the cat's designation as one of the world's worst invasive species. Despite this general adaptability, the close relatives of domestic cats, the African Wildcat (Felis silvestris lybica) and the Arabian Sand Cat (Felis margarita) both inhabit desert environments, and domestic cats still show similar adaptations and behaviors.
Impact on prey species
To date, there are few scientific data available to assess the impact of cat predation on prey populations. Cat numbers in the UK are growing annually and their abundance is far above the ‘natural’ carrying capacity, because their population sizes are independent of their prey’s dynamics: i.e. cats are ‘recreational’ hunters. Population densities can be as high as 2000 individuals per km2 and the current trend is an increase of 0.5 million cats annually.
