Alien cattle mutilations

Cattle mutilations have been happening for years. Many people have suggested that they were done by aliens. I will get quotes if you like.

Are these rouge aliens that want some other type of nutritional substances.

Are they looking for protein like beef? In spanish meaning carne?

Are they looking for carne asada nachos?

Are they stealing cows DNA to clone there own beef?

Also cows make milk, milk give you cheese. Beef and cheese.
