Which of the following is NOT one of the 4 fur types of rabbits?

The classification of rabbit fur types is an important aspect of understanding rabbit breeds and their characteristics. The four main fur types recognized in rabbits include normal, satin, and rex.

Normal fur is what most rabbits have; it is straight and lies flat against the skin. Satin fur is known for its unique sheen and soft texture, created by a special gene that alters the structure of the hair. Rex fur, on the other hand, is distinguished by its shorter, velvety texture, which has become quite popular in show rabbits due to its desirable feel and appearance.

Curly is not recognized as one of the standard fur types in rabbit breeds. Although some breeds may have features that resemble curls, such as the Angora breeds which can have curly, long fur, "curly" itself is not formally categorized among the recognized types. This distinction helps in effective breed identification and understanding their care requirements, emphasizing why this is the correct choice.
