WesleyB: I believe cats have some high charisma stat or something, in terms of CRPG lingvo. We have three cats in our household and despite all the amount of crap (mostly literal) and damage they give us we still tolerate it and love them.
My friend told me an amusing story - their farm had a fierce guard dog who wouldn't let any stranger in the territory without a bark and a bite.

HAD because one day some homeless cat showed up, moved into his doghouse, and they've literally became best friends.
Somehow. He also smoothed the canine a bit and made him quieter. Any attempts at separating them made the dog turn up his "violent disobedience" meters. So he permanently became a part of that farm.
Then that cat turned the barn into a feline swinger's club.
I had "dogriders" cats.
One time I was going outside and I saw a dog running like if its life depended on it, through the door´s frozen glass, though it seemed too tall. When I rushed outside, I got to see the dog just reaching the gate on its way outside and one of my cats riding it on top and jumping off of it just before the dog crossed the gate.
I wondered how the heck did my cat do that, so another day I saw a dog coming into the garden through the front gate and I rushed outside, albeit stealthly and hide behind a wall, watching the corridor where the dog was walking through.
Atop a platform there was on the garden was my cat crouching and watching the dog. Just when the dog walked through the corridor between the wall and the higher ground my cat was on, she jumped onto the dog and punced her claws. The dog was so confused and shocked that it howled and started running to the closest exit, while my cat was riding it just before it got outside.
They were two cats, three coloured female hunters, that not only hunted mice it seemed :P
