What does malocclusion refer to in rabbits?

Malocclusion in rabbits specifically refers to a dental condition where the teeth do not align properly, leading to issues such as overgrown or misaligned teeth. This often manifests as "buck teeth." When the incisors grow too long or develop unevenly, this can lead to difficulty in eating and other serious health issues. Thus, malocclusion is considered a significant concern in rabbit care and can indeed be a disqualification in show settings, as it impacts the animal's health and overall presentation.

The other options do not accurately define malocclusion. Irregular bone structure pertains to skeletal issues but does not directly relate to dental problems. Improper fur shedding relates to grooming and coat health and is separate from dental health. Excessive weight concerns the overall body condition of the rabbit rather than specifically addressing dental anatomy or function.
