AbstractThis study sought to determine whether a change in the abundance of feral cats (Felis catus) in three areas of England had occurred between the completion of a survey undertaken by the Ministry for Agriculture Fisheries and Food in 1986/7 and the turn of the century. In the event of a rabies outbreak occurring in Britain, feral cats would be one vector of the disease that would need to be controlled under the Rabies (control) Order 1974. A total of 741 “high risk sites”, found to provide appropriate conditions for feral cats, were surveyed between 1999 and 2000. The total number of feral cat colonies located within the survey areas was found to have fallen by 37% from 68 in 1986 to 43 in 1999/2000, translating to an estimated 212-247 fewer individual feral cats. Factories/trading estates and industrial premises continued to be the most common sites associated with urban feral cat colonies. However, the closing down of many traditional industries, such as mills and dockyards, and their replacement by more secure and insulated modern buildings, less amenable to feral cats finding warmth and food, had assisted the observed fall in numbers along with the effectiveness of neutering programs which are now taking place on many sites. Through this study information regarding feral cat colonies’ in urban landscapes as well colony size was gathered and fed into rabies contingency plans to help keep Britain rabies free into the future.

246 feral cats were shot on Macquarie Island, Australia, between Dec. 1976 and Feb. 1981. The sex ratio ( males : females ) was 1:0.8. The percentages of animals with tabby, orange and black coats were 74, 26 and 2 resp. [sic]. Of the 64 orange cats, 56 were males . The breeding season was Oct.-Mar., with a peak in Nov.-Dec. The number of embryos in the 14 pregnant females averaged 4.7 (range = 1-9). The size of the 23 litters that were observed averaged 3 (range = 1-8). Kitten survival to 6 months of age was estimated to be <43%.

Feral cats (Felis catus) occur throughout central Australia. In this study, we analysed the stomach contents of 390 feral cats collected between 1990 and 1994 from the southern half of the Northern Territory. Cats fed on a wide variety of invertebrates, reptiles, birds and mammals, including animals up to their own body mass in size. Mammals were the most important prey but reptiles were regularly eaten in summer and birds were important in winter. Invertebrates were present in the diet in all seasons. Carrion appeared in stomach samples during dry winters only and this has implications for future control of feral cats.

Inappropriate use of rodenticides by most market communities has resulted in a reduction in the population of feral cats (Felis catus) found in the market. If this continues, it can lead to the extinction of feral cat species in the area. This study aims to describe the level of knowledge and attitudes of the market community regarding the use of rodenticides and their impact on feral cats (Felis catus). This study used a survey method, namely interviews and observations of 28 respondents who claimed to have used rodenticides. The results showed that 35.7% of respondents had a low level of knowledge, 39.3% had a moderate level of knowledge, and 25% had a high level of knowledge. As for the attitude aspect, the majority of the community obtained quite good criteria with an average of 68.

Photographic Evidence

Feral cats (Felis catus) have contributed to the extinction of numerous Australian mammals and are a major threat to many species of conservation significance. Small mammals are considered to be those at greatest risk of cat predation, with risk typically inferred from dietary studies. However, dietary studies may provide only weak inference as to the risk of cat predation for some species. The most compelling evidence of predation risk comes from direct observation of killing events; however, such observations are rare and photographic evidence is even rarer. I present photographic evidence of a feral cat killing and consuming an adult female Tasmanian pademelon (Thylogale billardierii). This observation provides direct evidence that feral cats can kill prey up to 4 kg in body mass, with potential implications for the conservation of medium-sized mammals.

Significant Difference

ERADICAT®, a sausage-type meat bait, has been developed for use in managing feral cat (Felis catus) populations throughout Western Australia. However, concern about potential exposure of non-target species to bait-delivered toxicants has led to the development of a technique to more specifically target feral cats using a pellet. Research into the consumption, by cats and native animals, of toxic pellets implanted within the ERADICAT® bait has been simulated using ball bearings as a substitute pellet. Results from our work indicate that encapsulating the toxicant may pose less risk of poisoning to chuditch (Dasyurus geoffroii), woylies (Bettongia pencillata) and southern brown bandicoots (Isoodon obesulus) as they consumed significantly fewer ball bearings (P = 0.003, <0.001, <0.001) than semi-feral cats (P = 0.07). Theoretically, a toxic pellet will not reduce the effectiveness of the ERADICAT® bait as there was no significant difference between consumption of baits and the consumption of ball bearings in feral cats (P = 0.07). Therefore, baits containing a toxic pellet have the potential to be a more selective method to control feral cats.

The Impact

Abstract ContextRecent global concern over invertebrate declines has drawn attention to the causes and consequences of this loss of biodiversity. Feral cats, Felis catus, pose a major threat to many vertebrate species in Australia, but their effect on invertebrates has not previously been assessed. AimsThe objectives of our study were to (1) assess the frequency of occurrence (FOO) of invertebrates in feral cat diets across Australia and the environmental and geographic factors associated with this variation, (2) estimate the number of invertebrates consumed by feral cats annually and the spatial variation of this consumption, and (3) interpret the conservation implications of these results. MethodsFrom 87 Australian cat-diet studies, we modelled the factors associated with variation in invertebrate FOO in feral cat-diet samples. We used these modelled relationships to predict the number of invertebrates consumed by feral cats in largely natural and highly modified environments. Key resultsIn largely natural environments, the mean invertebrate FOO in feral cat dietary samples was 39% (95% CI: 31–43.5%), with Orthoptera being the most frequently recorded order, at 30.3% (95% CI: 21.2–38.3%). The highest invertebrate FOO occurred in lower-rainfall areas with a lower mean annual temperature, and in areas of greater tree cover. Mean annual invertebrate consumption by feral cats in largely natural environments was estimated to be 769 million individuals (95% CI: 422–1763 million) and in modified environments (with mean FOO of 27.8%) 317 million invertebrates year−1, giving a total estimate of 1086 million invertebrates year−1 consumed by feral cats across the continent. ConclusionsThe number of invertebrates consumed by feral cats in Australia is greater than estimates for vertebrate taxa, although the biomass (and, hence, importance for cat diet) of invertebrates taken would be appreciably less. The impact of predation by cats on invertebrates is difficult to assess because of the lack of invertebrate population and distribution estimates, but cats may pose a threat to some large-bodied narrowly restricted invertebrate species. ImplicationsFurther empirical studies of local and continental invertebrate diversity, distribution and population trends are required to adequately contextualise the conservation threat posed by feral cats to invertebrates across Australia.

AbstractDoha city has a high feral cat population and studies of hospital records in Doha have shown that human toxoplasmosis also occurs. Clearly, there is a need to understand the role of cats as vectors of human toxoplasmosis in the city and as a first step we assessed the extent of patent Toxoplasma-like coccidial infections among feral cats. Oocysts in cat faeces were detected between June 2008 and April 2010, from a range of locations radiating out of the city centre in concentric semi circular/elliptic rings and by north, west and south divisions within each of the rings. In total 4,652 cats were sampled and overall prevalence of oocysts was 9.1%. Prevalence was 10.1% in the first summer, and then dropped to 8.4% in the following winter and further to 6.8% in the next summer before rising to 10.6% in the final winter of the study; this interaction between annual period and season was significant. There were also significant changes in prevalence across each of the consecutive months of the study, but no clear pattern was evident. Prevalence did not vary significantly by city sector and there was no difference in prevalence between the host sexes. We conclude therefore, that despite minor and significant perturbations, the prevalence of patent Toxoplasma-like coccidial infections among cats in Doha is remarkably stable throughout the year, across years and spatially within the city’s districts.

Management of feral cat (Felis catus) populations is currently limited by the lack of a control technique that is cost-effective, target-specific and suitable for broad-scale application. This paper describes two non-toxic bait acceptance trials undertaken on French Island in Western Port, Victoria in south?eastern Australia. Moist meat baits were injected with the marker Rhodamine B (RB), and surface distributed along the existing road and firebreak network. Subsequent trapping of feral cats facilitated collection of whiskers, which were analysed using ultraviolet fluorescence microscopy for the presence of RB marking. Twenty-four and forty-seven cats respectively were recovered in each trial with fifty per cent of these individuals found to have consumed at least one bait in either trial. Results are discussed with reference to the development of a felid-specific toxicant baiting technique.

Focus: Kingston Feral Cat (Felis catus) PopulationLocation: Greater Kingston AreaIssue: Released domesticated cats have established feral populations within the Kingston area. Predation by the feral cats has caused damage to the local bird and small mammal populations. The cats also displace other mammals that have previously occupied the same ecological niche. Furthermore, the increased cat population has led to an increase in the flea and disease count. Overall they decrease biodiversity in the Kingston area. Objective: We aim to promote and inform the general public of this occurrence, so that the communitycan be involved with helping manage and decrease the damaging effects of the feral population. Methods:1. Survey a local colony of feral cats to further understand the extent of the problem.2. Work with local conservation initiatives (ex. Kingston Spay and Neuter Initiative) to gain hands onexperience in dealing with the feral cats.3. To raise awareness by utilizing social media (creating images people want to share on Facebook,Twitter, Tumblr etc.)Ultimate goal: With this project we hope to alter the problem of feral cats with a two-fold solution. By increasing public awareness we hope to decrease the release of domesticated cats into the wild, promote owners spaying and neutering their pets and encourage others to perform further work. We hope to utilize our own skills and gain experience by working on the ground with local initiatives to learn the best methods to tackle this issue.
