SEATTLE, Washington- Cats have quite a few characteristics that make them better to have around then dogs. The first one is obvious - the typical cat has much more contempt for humans than the typical dog. I like that.
One other thing is the cleanliness angle. I was at a friend's house last weekend, and they have a dog, and the dog smelled a little bit. Not a lot, probably the average dog smell, but it's noticeable and this is in spite of the dog getting bathed.
I've had my cat for 11+ years and never cleaned her. Yet, I just took a deep sniff of her torso, and she smells like she just popped out of the clothes dryer. They handle this themselves.
