I'm not biased at all I promise. But there is something very charming about meeting an outdoor cat. It's not like a dog, you don't have to worry if maybe the cat is protecting something, maybe you shouldn't get too close. The cat will do that part. If the cat comes close then you think oh shit maybe it wants me to touch it. But that's where you are wrong, because it's a cat. It's going to detect instantly that you want to touch it, flick it's tail, and take a few steps back in the other direction. Turn its' back to you. And sit for a bit. But if you are a weird cat person like me you will sit there and try and flirt with it and see if it will come say hello. And you can scratch its' neck for a brief moment before it flicks its tail and decides that was enough and wanders off to do whatever sort of cat thing outdoor cats do. Dogs don't act like this. And I think thats why people like the idea of wandering cats.
