Indeed it is true. A mule has a horse mother and a donkey father. Goofy and cute, mules definitely belong here on ACAD. Unfortunately, mules are often sterile by nature, meaning that it is rare for a mule to have offspring of its own.
So, what do you think of this goofy little mule next to its mother? Isn’t it so sweet looking?
