Pigs

A lady calls near the end of a fifteen call day.
She drives by a small ranch or farm everyday and sees a field full of goats, which she loves to watch. They recently add pigs.  The women is concerned because the pigs are in a smaller area.  There is a cover for the animals, but there is mud.
"Pigs are smart animals and don't have to be in mud."
-Okay, so what is the issue
"Isnt that animal neglect or abuse?"
- So they are not underfeed, have shelter?
"Yes"
-ma'am that is not abuse or neglect because you don't like how they are kept.
