I live in an area with citrus orchards. I was away a couple months and my daughter didn’t bring in the bird feeders at night. I came home to rats falling from the elm trees. It was bad, really bad.
I tried live traps, electronic traps, nothing was working.

This feral cat showed up and after a couple months not one rodent survived. It took another couple months to get her to trust me enough to catch her. She earned a place of honor in our house.

I can tell you the difference between our useless mouser cat and this amazing rat killer. You need to be really careful playing with her. Just a tiny sound or movement she notices. A piece of string and it becomes a game of life and death.

Visit a shelter and check out which cat goes for the kill if you make slight scratching sound, bring a string or feather. You will be able to tell the killer
