Maybe you can't kill the cow, but if it dies by natural means it's fine

Will a ufo work? They usually kidnap/destroy cows.

 

Ufos are a transport medium like any other (that means, when you summon it, it comes up empty). Dunno what happens if you put an alien in there. Still, I don't think I've noticed any particular ability for UFOs (other than the fact that they fly)
