When having a pet, you have to be ultra responsible. A cat is easier to care for, but even they have needs that don't just go away when you want them to. And a dog is even more responsibility. Dogs have been domesticated, but sometimes we forget their size, their nature, and where they come from. They do have that violent and animalistic nature in them, and the teeth and claws to do damage.
A cat, though more capricious and moody in nature, simply isn't large enough to do real damage. In the story below, the protagonist is a man who's a regular at the local dog park, and claims the vibe there is a pleasant energy, filled with respectful regulars. One day, a new couple shows up not only with an aggressive Pitbull (sorry Pitbull's), but also with an orange tabby cat. For the sake of the cat, it seems awfully uneducated and blindly dangerous to bring a cat to a dog park, but read the full story to find out what happens.
