One study (there's always at least one...) insists that cats aren't even that good at rat control. https://www.smithsonianmag.com/smart-news/cats-are-surprisingly-ineffective-keeping-urban-rat-populations-check-180970428/
I have seen that one before! It’s a pretty interesting read. I wonder if they are less likely to hunt mice as well in favour of things like birds instead?
