What is a bare spot on a cavy?

A bare spot on a cavy refers to a section of the animal's skin that is devoid of hair. This can occur for several reasons, such as health issues like skin infections, mites, or excessive grooming. It is important for owners to monitor their cavies for bare spots as they can indicate underlying problems that may need veterinary attention. Recognizing a bare spot is crucial in ensuring the cavy's overall health and well-being. The other options do not accurately describe a bare spot, as they either relate to behavior, health, or breed characteristics that do not involve the loss of fur.
