The first two cats I got literally came from a barn in Wyoming county. The brother and sister pair are now almost 14 years old. They're great companions and they tolerate me well. The third cat was an adoption from a friend that could no longer keep him. He spends his time sleeping in a box that's on top of the chest freezer in the basement. He guards the coal stove with an air of laziness any cat would be proud of.
I would take more if I could, but three is enough. If you want a pet that is super easy to take care of, a cat is the perfect choice. They require some cat food, water and a spot they can call their own. Just remember, they own you, not the other way around. Cats rule, dogs drool.
