Terrific essay -- great job! I do so love this pairing. :-)

May I point out one wee typo?

They compliment one another in looks, personality and needs.

I believe "compliment" (http://dictionary.reference.com/search?q=compliment) here should be "complement" (with an "e") (http://dictionary.reference.com/search?q=complement).

Thanks so much for all the love and hard work you obviously put into this essay.
