I said neither because first, cats don't really care until the can opener starts. And they always show you their butthole when they walk away. Then you have to have a litter box. Some will argue cats are healthy in clean, yet they have an open box of poo in their house. And they track that around the house and on your tables and counters between their little kitty toes. Ya know, that isn't granola and raisins there on the table!!
Dogs are just loud and bark and have bad breath and they eat cat poo out of the litter box and then want to come and lick your face

They also destroy your yard. Then there are fleas, ticks, and muddy paws, then the weekly baths, heart worm pills and picking up dog poo in the yard

. Maybe I am just too lazy to own such a creature. I feel they are best admired from afar.
