I know you specifically asked about rats but domestic cats are killing machines. https://pubmed.ncbi.nlm.nih.gov/23360987/ We estimate that free-ranging domestic cats kill 1.4-3.7 billion birds and 6.9-20.7 billion mammals annually.
A wild cat would have parasites, a few still healing wounds, one eye and one of it's legs has bones did not heal quite straight. This is a cat that "naturally" hunts mice and birds. Compare that to a suburbian cat which is healthy, well fed and it's biggest health risk is obesity
Was on the porch the other night and saw her take a 15 foot dump out of a tree with a rat ( big one too). She landed on top and made short work of the rat. She's an excellent ratter.
