The Canadian kitten wins, though I must add that I at first thought it was blind in its right eye (which detracted from its initial cuteness).
Personally, I find Norwegian kittens to be the cutest of them all; they too have national health care, will (hopefully) soon be able to marry their lesbian life-partners, and live in the current top-ranked nation in the UN Human Development Index. Rabies is non-existent here and even terrorist kittens receive due process by law (much to popular and tabloid frustration and outrage). It is also illegal to spay female cats in Norway.
Oh, and kitty-eating reptile pets are also illegal here (along with all other reptilian pets).
