Well my roomates are cat people, I am a dog person.
My roomates always say they cant believe i like my dog since she needs me to let her out to go to the bathroom, fed her etc,,,,,where as their cats do this on their own so they feel they are more self reliant. But my point is how self reliant and independant is an animal who takes a crap IN your house? LOL I find that to be a HUGE turn off towards cats personally.....and I prefer a animal who actually seems to appareciate walks, car trips, playing fetch etc.....sometimes our cats don't even want to be pet.
In the end, its a personal preferance for sure, and one is not better over the other. Good luck with your new dogs!
