I have always been more into dogs growing up, but since my uncle got his cats some years ago I started to like cats more. I don't have pets but I think cats are much easier to have, sure for someone lazy like me. My cousin got a dog recentelly, and stuff like having to take for a walk is so tiresome. Then dogs seems so needy, you need to take a time in the house to give them some attention, they jump on you for attention, while with cats is more like the opposite, I like playing with other's dogs but I think I would get bored quickly to have one at my place.
Oh and on the shit stuff, cats seems much more hygienic, maybe its because her dog is still young, but sometimes he shits and piss all over the apartment, and of course he is curious about on how his stuff tastes like, maybe that's why some dogs have such bad breath. While I don't think even the cats that live on my neighborhood's streets have any bad smell.
