The two-year-old from Pilton, Australia, shares her family home with the cub who is called Saskia.
Saskia is being hand-reared by Maddi's parents, because her mother couldn't produce enough milk to feed her.
Once Saskia is older, the plan is for her to return to live at the local zoo, but there's no word on when this will be, or how big she will be by that point.
While no one can deny Maddi's love for Saskia, this footage made us a little uneasy. One swoop of those claws could spell disaster.
