What is a common consequence of poor sanitation in rabbit facilities?

Poor sanitation in rabbit facilities can lead to a variety of health issues among the rabbits. When living environments are not kept clean, harmful bacteria, parasites, and diseases can thrive, which directly impacts the health of the animals. Rabbits can be particularly susceptible to respiratory infections, gastrointestinal diseases, and other systemic health problems due to unclean conditions.

Maintaining proper sanitation is crucial in preventing these health risks; providing adequate cleaning routines helps ensure that the rabbits live in a safe environment where they can thrive. In contrast, an increase in weight gain or improved coat quality is unlikely to result from poor sanitation, and while enhanced breeding might seem relevant, it is fundamentally linked to the overall health and well-being of the rabbits. Therefore, the most direct consequence of poor sanitation is the emergence of health issues, making it the correct answer.
