Which of the following is NOT a general disqualification for rabbit breeds?

Old age is not considered a general disqualification for rabbit breeds because it does not inherently affect a rabbit's physical appearance or health in the same way that specific health conditions do. Disqualifications typically relate to observable traits or conditions that violate breed standards or suggest poor health.

Blindness, abscesses, and cold symptoms are all specific health issues that can significantly impact a rabbit's overall condition and presentation. These conditions are typically considered disqualifying because they can indicate deeper health problems, affect the rabbit's quality of life, or prevent them from meeting the breed standards set for shows and competitions. Therefore, while old age may influence a rabbit's health and vigor, it is not a direct disqualification under the breed standards.
