I have never seen any studies that implicated cats feral or otherwise as being as significant a detriment to native species of wildlife the way introduced species and even collectors have been.

I am actually a cat lover. I have two old cats and they do get out into the back yard, but they don't leave the yard. One of them has killed a few small rodents, a squirrel, and numerous Med. Geckos. (I don't mind the med geckos, as I hate all non-native species. I round up med geckos whenever I need snake food for a picky feeder).

That said, you can't have looked very far to find research into the impacts of feral cat predation. There are hundreds of such studies, with contradictory results. Try searching google scholar and you will find lots of references.
