(If you're alluding to the idea that the "black death" plagues were worsened by cat culls, that's an oft-repeated story but somewhat dubious with regard to verifiable facts. Cats themselves can carry the plague bacteria & transmit it to humans – eg https://www.nytimes.com/1994/04/08/us/house-cats-spread-huma... – and even regions where cats are superstitiously cherished suffered repeated plague outbreaks.)
