paper-trained
Taught bathroom sheets
Paper-trained describes a pet, usually a puppy, that has learned to relieve itself on newspaper or absorbent pads rather than outside: The breeder said the puppies were already paper-trained.
The term extends figuratively to people who've learned basic rules of civilized behavior: He's not even paper-trained—he leaves his dishes everywhere.
