The Tulsa World reports that 34-year-old Mary Elizabeth Moore was charged in Delaware County court this month.
The children, aged five and three, are severely malnourished and have been placed on a special diet with nasal feeding tubes. They are in state custody.
An affidavit says the older child told Department of Human Services workers that she ate dog faeces. The arresting officer noted the child had parasitic pinworms.
The girl also told investigators that her mother’s boyfriend “throws bottles” at her younger sibling.
The affidavit says Moore denied starving her children and feeding them dog faeces.
Her court-appointed attorney, Lee Griffin, didn’t immediately return a phone call Saturday seeking comment.
