Which pet do you enjoy playing with more--cats or dogs?

I prefer cats in game, but that is largely because I find it annoying to have to take the dog for a walk so often. Seasons especially made it a pain for me in one of my saves because the dog would want to go for a walk, but it was raining almost all the time whenever my sims were around to walk the dog. I'm not taking a vacation day to walk the dog.
