Cats are fine with me, mostly. I have loved a few. I have disliked several.
My dog hates nearly everyone. She loves exactly 4 people forever and ever but she wishes great pain and slow death upon everyone else. Her bark alone has terrorized many, her Death Stare even worse. And being the size/strength that she is... we have a very reliable guardian.
Two brother dogs we had (RIP bros) were distinct animals: one hated everyone but his immediate family and would defend us until his dying breath, even from other loved ones. But to us, he was the sweetheart amongst sweethearts. His larger, far more intimidating (looking) brother would casually stroll away with strangers or anyone that paid even an ounce of attention to him. He loved everyone.
