My kids are old enough now we don't have to worry about that issue. But I remember how it was!
When I was growing up we always made pets out of the livestock, but there was never an issue having it for dinner. Guess our stomachs' overruled any emotional attachment. It was always understood that the reason for having that animal in the first place, was for food.
I always got more steak if I reminded my little sisters we were eating "Pete" and "Tilly." Worked like a charm!
If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
Worked like a charm!
