I do not know of a practical way to keep a cat from bringing into the house a kill. This is one of the most disagreeable issues concerning cat ownership. However, with my managerie, they have pretty well cleared out the premises of unwanted varmets; snakes and gophers. This was the main reason I took in a stray cat about 6 years ago -before I became "educated" enough to understand about breeds and individual temperments.
