CONCLUSION
The impact of feral cats to the Australian environment has evidently become a serious matter. They have caused negative influences to the Australian wildlife and to the extinction of some native fauna. They are a major cause of decline for many land-based endangered animals such as birds and small to medium-sized mammals, especially to Northern Territory, Western Australia and in central Australia. However, there is no conclusive evidence that feral cats have resulted in population of native mammals. The Government have enforced different programs, which basically focuses on the eradication of feral cats, to control their population among Australia involve classic method and chemicals technique. Overall, the findings of those research suggest that the impacts of feral cats to Australian environment need to be continuing analysed to indicate whether they should be given animal rights or be reduced.
