Abstract: A collapsible potty training assembly for collecting feces and urine during potty training includes a panel and a bag that is collapsibly coupled to the panel. The panel is selectively gripped to position the bag beneath a user when the panel is gripped. Thus, the bag receives feces and urine from the user when the user is potty training. A drawstring is slidably coupled to the bag and the drawstring selectively closes the bag. A pad is positioned in the bag and the pad is comprised of a fluid absorbent material to absorb the urine.
