What is an appropriate way to cool a rabbit during hot weather?

Cooling a rabbit during hot weather is critical to their health and well-being, as they are sensitive to heat. The method of putting wet socks on their ears provides a way to help reduce their body temperature. Rabbits often cool themselves through their ears, which are rich in blood vessels. By wrapping their ears in cool, damp fabric, you can help promote heat loss through this vascular area, effectively providing them a way to cool down.

In contrast, placing rabbits in direct sunlight would increase their body temperature and could lead to heat stress or heatstroke, making it an inappropriate choice for cooling. Shutting all windows and doors of their hutch would inhibit airflow, trapping heat inside and further elevating their stress levels. Feeding them cold vegetables might provide some hydration, but it does not directly cool their body temperature as effectively as the wet socks approach. Thus, the most effective method for cooling a rabbit in hot weather is the one involving wet socks on their ears.
