Are Relationships Between Different Species "Normal"?

[Lexedrine]

While I do not think, say, a marriage between a human and a wolf, or between a rabbit and a cat would always be considered "normal", in a perfect world, I do not think these would really be considered an illness like they are in society today.

Remember, I'm talking about a perfect world, so don't worry about anything like "it's a money or popularity stunt" or "they're not a match".
