How tiny can mongeese get? This baby dwarf mongoose is just a few inches long, and will only grow up to be about a foot in length.
That's not a baby horse you're looking at—it's Thumbelina, the world's smallest dwarf miniature horse! She's only about a foot-and-a-half tall and weighs 57 pounds! They don't make 'em any tinier or squeer than her.
