Okay i work with cat rescue. I get so many farmers and even people wanting cats that will hunt. Here is the issue most cats will hunt mice. but rats is something else. Few cats wanna get dirty and take on large rats or stoats. But some cats do. Imagine making a breed of cat meant for farms that are exceptional killers? Instead of getting ten cats you would just need one cause it would seek everything out like a terrier? Is it possible? I know so many barns looking for rat killers. If such a cat was bred it could even take on small predators like mink. The worry is that they might go after the birds then. But my bengal wont touch my birds and kills all the rats. Shes f4. Its just a thought not going to try it or anything. Curious why no one has over the years. Barns are flooded with 200 cats they say the more the better the less rats. But what if they only needed one.
