Why can't I have a cow?

Connor has decided that he wants a pet and that pet needs to be a Cow because he doesn't like cats and dogs and Cows don't go potty.

But the Cows do have to go potty....Connor said "Okay, if the Cow has to go potty, he will just Moo and we will let him out." (Apparently, the Cow will get to stay in the house).

But Cows live on the farm...Connor said "Okay, we will paint the house red and it will be a barn."

I'm sure he would also name it Otis...from his new favorite Cartoon, Back at the Barnyard.

Day 2 - the cow discussions continue...Did you know that Cows can make us milk? What planet are cows from? Did God move them from another planet to Earth?
