While subsidised populations of feral cats are known to impact their prey populations, little is known about the ecological impact of inside/outside hunting cats (IOHC). We studied IOHC around a suburban nature preserve. Mail surveys indicated an average of 0.275 IOHC/house, leading to a regional density estimate of 0.32 IOHC/ha. A geographical model of cat density was created based on local house density and distance from forest/neighbourhood edge. IOHC hunted mostly small mammals, averaging 1…

The small home ranges and large local ecological impacts of pet cats
Domestic cats (Felis catus) are a conservation concern because they kill billions of native prey each year, but without spatial context the ecological importance of pets as predators remains
Urban cat (Felis catus) movement and predation activity associated with a wetland reserve in New Zealand
It is suggested that domestic cats will exploit wild habitats but that their potential impact will have both positive (predation of introduced pest species) and negative (occasional direct predation) effects on native wildlife.
Anthropogenic factors influence the occupancy of an invasive carnivore in a suburban preserve system
The results suggest that free-ranging cats are rare within suburban preserves in the Chicago, IL metropolitan area, and that these cats are most likely owned or heavily subsidized by people (which pose different risks and management challenges than truly feral cats).
Activity of free-roaming domestic cats in an urban reserve and public perception of pet-related threats to wildlife in New Zealand
Across the globe there is an increasing number of initiatives promoting biodiversity in urban areas – both for the benefit of native wildlife and the people who live in cities. In these situations,
Occupancy and abundance of free-roaming cats in a fragmented agricultural ecosystem
Context Free-roaming domestic cats are a widespread invasive species, occurring throughout the globe in urban and rural environments alike. However, robust estimates of cat occupancy and abundance,
Free-ranging house cats in urban and rural areas in the north: useful rodent killers or harmful bird predators?
The prey of young cats was more diverse than that of older, more experienced cats, and “Super predator” cats should be kept in the house, especially in urban areas to prevent predation on birds.
Urbanisation influences range size of the domestic cat (Felis catus): consequences for conservation.
Domestic cats (Felis catus) are the most abundant predator in many urban ecosystems, and their ranging behaviour will help determine predation rates. To investigate how degree of urbanisation affects
Ranging characteristics of the domestic cat (Felis catus) in an urban environment
In many countries, high densities of domestic cats (Felis catus) are found in urban habitats where they have the potential to exert considerable predation pressure on their prey. However, little is
Movement and diet of domestic cats on Stewart Island/Rakiura, New Zealand
Domestic cats (Felis catus) in Halfmoon Bay, Stewart Island/Rakiura, were tracked to assess the potential for incursions into native forest around the township, and into Rakiura National Park c. 5 km


Demography and movements of free-ranging domestic cats in rural Illinois
Cat populations were studied on a rural area in eastcentral Illinois from 1977 to 1981 to determine: (1) the demography of the free-ranging cat population associated with rural residences; (2) the feeding behavior of these cats; and (3) the summer range and use of cover by a sample of radio-monitored cats.
The present report describes and discusses the annual and seasonal predation by these cats from 1 January 1968 through 31 December 1971, and their predation on non-mammalian vertebrates (various birds, reptiles, and frogs) is tabulated to round out the account.
Predation by domestic cats in an English village
Domestic cats would appear to be major predators in this typical English village, but fewer prey were caught in winter; cats also caught less on wet days and windy days.
Predation of wildlife by domestic cats Felis catus in Great Britain
Investigation of potential management practices that could reduce the numbers of wild animals killed and brought home by cats will be useful for wildlife conservation, particularly in suburban areas.

Although cats are only one factor involved in the reduction in the numbers and diversity of Australian wildlife, restriction of the outside activities of cats is likely to diminish predation, particularly in areas close to native vegetation.
The role of spatial scale in understanding responses of medium-sized carnivores to forest fragmentation
Free-ranging domestic dogs and cats did not respond to the proximity of habitat edges in summer but showed a strong affinity for edge habitats (especially those associated with human dwellings) during winter, and raccoons were more abundant in landscapes characterized by a diversity of cover types.
Small mammals and songbirds constitute a large proportion of the diet of free-ranging domestic cats (Felis catus) (Parmalee 1953, Eberhard 1954, Jones and Coman 1981, Liberg 1984, Churcher and Lawton
