Its much easier to leave a cat home alone with really full food and water dishes so you can go wander around for a week or two in an empty labyrinthine wasteland full of space-pirates in need of killing and magic sticky notes left for you by the psychic aliens that raised you.
Do that with a dog, you'll have a house full of poop and a very, very neurotic and depressed pooch. Do it with a cat, and you'll get a few minutes angry/dissappointed stare plus a more difficult litter box cleaning.
