Mine are checked several times throughout the day, with constant shade, strong airflow from fans, fresh water, and frozen bottles or chilled tiles available when temperatures climb. I also watch closely for early warning signs such as drooling, weakness, rapid breathing, poor coordination, hot ears, or skin that stays tented when gently lifted. Heat stress can become an emergency very quickly, so prevention matters more than waiting until a rabbit is already in trouble. Keep cages out of direct sun, maintain good ventilation, refresh water often, and move any struggling rabbit to a cooler area immediately. What methods are working best in your rabbitry this summer?
