Cats, heck I've seen them flush toilets, tear up rolls of paper towels, and do amazing shit I haven't seen in my life. 개 are ok to but they are sometimes lazy, it's fun how 당신 play with them using there toys.
Both but 고양이 are what we call "cunning" and 개 are what we call "intelligent", 고양이 usually win because they cheat...evil plotting little things but 개 can learn 더 많이 unlike ignorant cats.
