It's interesting that dogs are seen as the more practical, helpful pet. And certainly for much of history, that was true. However, in a modern, urban environment, I'd say the situation has reversed. Apart from the intangible, emotional companion benefits, I'd argue there isn't much practical use of a dog for a city-dweller. On the other hand, a cat at least has the benefit of keeping unwanted rodents out of your apartment.
