What is the best way to actively cool a rabbit during high temperatures?

The most effective method for actively cooling a rabbit during high temperatures is to use a fan and apply wet rags to their ears. Rabbits have a unique anatomy that allows them to regulate their body temperature primarily through their ears, which have many blood vessels close to the surface. When wet rags are placed on the ears, they facilitate cooling through evaporation.

Fans help by increasing airflow around the rabbit, creating a breeze that can also aid in reducing their temperature. This combination allows for effective heat dissipation, keeping the rabbit comfortable during hot weather.

Providing more food and water is essential for overall health, but it does not actively cool the rabbit or address the immediate need for temperature regulation. Taking rabbits for a walk can expose them to heat, which may be counterproductive and stressful. Keeping rabbits indoors at all times may help in controlling their environment, but without airflow and moisture, it does not directly provide the cooling benefits that a fan and wet rags can offer.
