Rabbits require daily exercise outside of their cage to maintain physical health and mental well-being. The exercise session should last at least one to two hours. During this time, it's crucial to bunny-proof the area by removing hazardous items like wires and toxic plants and providing safe toys and chewables. This not only helps in preventing boredom and promoting natural behaviors like hopping and exploring but also in preventing health issues related to inactivity, such as obesity and gastrointestinal disorders. Regular exercise contributes significantly to a rabbit's overall quality of life.
