The animal ballot is super, but I think it might be nice to randomise the order in which the options appear, to eliminate bias towards things which happen to be first alphabetically (known as the "ballot order effect", e.g. http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=6065005&tag=1).
In this case it's complicated by the fact that alpacas are the cat's whiskers, so might have got lots of votes anyway; but it's mighty suspicious that, given there are two places up for grabs, the top two animals have a large number of votes...
