Only had dogs so I'm biased and there is a negative thing that makes lean towards cats. Having a dog is sometimes annoying due to having to be limited to a certain amount of hours away from home until having to go out with them again, and I don't know what it is like having cats so correct if I'm wrong, you can leave them unattended a little longer than with dogs because they're a little more self sufficient when left with food, water and a litter box. Can a cat be left alone at home for 24 hours for example?
