Apparently, there's just something about the bovine critters that aliens just can't get enough of. And in Abducted Cow, it's your job as an alien to kidnap, steal, and defend your cows from other aliens. The card game is up on Kickstarter now.
From the campaign:
You are an Alien controlling a UFO. Coming upon Earth you develop an unhealthy fascination for the creatures we call cows.
It has now become a race to fill your ship with these animals.To win, you will use advanced UFO technology to attack, defend and steal the cows of your opponents.
The campaign is about 1/3 to its goal with still 21 days on the clock.
