The cat crap and urine caused me to stop gardening. I can't bird watch in my yard now. The cats killed the nesting birds on my property.
Cats were part of the natural order of things in Africa 5000 years ago before they were domesticated. They are as much a true wild cat now as poodles are wolves. Without cats, the hawks, owls, snakes, and other natural predators would control rodents, as they always have. As it is now our natural predators are facing unnatural competition from the cats, who are subsidized by people.
