Which of the following is a general disqualification for rabbits?

Blindness is a general disqualification for rabbits because it severely impacts their ability to interact with their environment, navigate and respond to various stimuli, which is essential for their welfare and well-being. In a competitive setting, such as fairs and shows, being sighted is critical, as judges assess both the physical attributes and the overall health and functioning of the rabbit. A rabbit that is blind cannot perform in the way that a fully sighted rabbit can, leading to an evaluation that does not accurately represent its breed characteristics or show potential.

In contrast, while small ears, a missing tail, and curled whiskers may be considered undesirable traits or faults in show rabbits, they generally do not rise to the level of disqualification. These qualities may affect a rabbit's placement in a competition, but they do not necessarily impact its basic health or ability to live comfortably. Therefore, they wouldn’t disqualify the rabbit from being part of the fair in the same way that blindness would.
