Looks like a full vote right now is worth 35 NeoxAg~ NeoxAg is worth 0.028 right now so that vote is worth right around 1 Steem (you get half that). So 10 Cats should get you roughly 0.5 Steem per day in votes. Not the greatest return considering 10 Cats making 10 Kittens even at reduced prices will get you much more value.
