A cat. Dp has never had pets and just doesn't get the point or see how much they have to contribute to a family unit. Also, he's allergic so the ones least likely to affect him are pricey. Add to that the fact that no matter how hard I try the place is never completely clean and he thinks a feline companion would only add to that and I really have my work cut out for me ever making it happen.
I'm an optimist, though (not to mention persistent )
