Can 2 rabbits be left alone?

Could you elaborate on the potential implications of leaving two rabbits alone? Are there any specific concerns that arise from such a scenario, particularly in terms of their well-being and safety? Do rabbits require constant supervision or are they capable of self-care to a certain extent? Are there any environmental factors that should be taken into account, such as the size of their enclosure or the availability of food and water? Additionally, are there any behavioral issues that could arise if the rabbits are left unsupervised for extended periods? Your insights into this matter would be greatly appreciated.
