Got one of each.

The dog is a good friend but a bad roommate. The cat is the opposite. In the house, I pick the cat. Outside, I pick the dog.

Bonus story, I took her for what was supposed to be a one hour walk yesterday and ended up being gone for three. Something about a dog makes people want to approach, tell a story, ask questions. It's a very refreshing and enriching way to enjoy an afternoon.
