Pet or Foods? Who can decide it? Who is the master? We are quite illogical when we try to decide what can be eaten and what cannot be eaten.

Foods is critical because we could hardly be survival without foods. We have been brought up to eat certain foods, sometimes eating unusually to show our own exaggeration.

The person eating one's pet is the person who never has his own pet.
The person having his own pet would never be able to chose his pet as foods.

These is no border against PET and FOODS. The ruler is just in everyone's mind.

It means it could only be decided by yourself what Pet is and What Foods is.
