What is a baby kangaroo called?

A baby kangaroo is called a joey, which is a term specifically used to refer to the offspring of marsupials. This is important to note because the term “joey” applies not only to kangaroos but also to other marsupials, including koalas and possums, highlighting its connection to this group of animals that carry and nurse their young in pouches.

The other options refer to different types of baby animals: a kit typically refers to a young fox or a young rabbit; a pup is commonly used for baby dogs or seals; and a cub usually denotes a young bear or big cat, such as lions or tigers. Therefore, while these terms are appropriate for their respective species, they do not apply to kangaroos, making "joey" the accurate choice in this context.
