I haven't always been one, even though I don't remember life without cats. Our first was Fido, a surly black-and-brown tabby who was treated very shabbily, I think. He had a big chunk missing from one ear, lost in a fight, no doubt; I'd hate to see the other cat. Fido was an indoor/outdoor cat, and when his nose started looking like something had been gnawing on it, we all figured he had just found himself in another back alley rumble or something. Turned out to be cancer, and by the time he found his way to a vet, it was too late. Mom took him there and never brought him back.
