What is required for animals to travel?

Animals must meet several requirements to travel safely and legally, which often includes being fit and healthy, being vaccinated, and having the appropriate travel permits.

The correct answer encompasses all these aspects. Being fit and healthy ensures the animal can handle the rigors of travel without undue stress or risk to their wellbeing. Vaccinations are often necessary to protect the animal from diseases, both for their own health and to prevent the potential spread of diseases that could affect other animals or even humans in different regions. Additionally, travel permits are often mandated to ensure compliance with local regulations and to help track and manage animal health and biosecurity during travel.

While being fit and healthy is crucial, it is only one part of the comprehensive requirements that facilitate safe and responsible animal travel, making the comprehensive option the most appropriate choice.
