Cats, by nature, don't do anything for the fun of it. They are honing their skills or killing for a later feed. Cats are a lazy and relaxed animal and don't like to do anything unless they absolutely need to. So they won't 'just go out and kill something because they feel like it'. They are killing it to hone skills and will eat it later or offer it to someone or something else later. Cats do not waste energy or food. They are natural conservationalists in their own rite...which is what explains the inordinate amount of time they spend napping.,,,you never know when they are going to need that energy.

In other countries, cats roam freely and kill off all other rodents and this is the norm and acceptable behaviour. Why? Because other 'pests' like squirrels and rabbits get into attics and crawl spaces of homes and really cause major damage and cats are seen as a natural and pesticide free way of maintaining that problem.

Unfortunately here in North America, it is viewed upon as a terrible thing to let nature take it's course, and we are expected go against nature and against animal ethics and lock them up like prisoners keep them from living their natural instinctural ways.

So, keep your cats inside, and when your neighbour starts to have her attic and crawl space eaten by squirrels and rats because your cats aren't helping, tell her to call her local pesticide company and have them extract the pests for tons of cash and pollute her home poison the environment with the chemicals needed to do it the unnatural way.
