So I have to say I prefer dogs to cats. This is due, no doubt, to the fact that a fabulous fawn-colored boxer was my constant companion from the time I was born until she died nine years later. There isn't a picture of me when I was a kid that doesn't include my peerless dog. I still have dogs--Aggie (a sweet, mildly neurotic Field Spaniel) and Zora (an enormous Newfie who slobbers A LOT). Can't imagine my life without them, frankly.
A writer needs a cat to sit on her desk while she writes. That's because writers are trying their hand at magic--conjuring up something from nothing. And as everyone knows, conjurers need their familiars. Which is why I have three cats. Can't imagine my life without them either.
