When do mammals typically begin to regulate their own bowel movements and urination?

• A. Not until weeks after eyes open.
• B. Shortly after their eyes open.
• C. Immediately at birth.
• D. Never; external stimulation required.

Answer: (B)

Elimination control develops as the nervous system matures after birth. Newborn mammals rely on the caregiver to stimulate urination and defecation through grooming or perineal stimulation. Once the eyes open, the animal is at a developmental stage where more voluntary control begins to emerge, so regulation of bowel movements and urination tends to start shortly after this milestone. It’s not immediate at birth, and it isn’t delayed for weeks beyond eye-opening. After eyes open, you’ll generally see the animal start to regulate elimination more on its own, though it may still need some prompting or assistance in the early stages.
