Which factor is not important in maintaining rabbit health?

Feeding commercial pellets is indeed a common practice for rabbits, but it is not the sole factor that determines their health. While these pellets can provide necessary nutrients, focusing exclusively on them overlooks the importance of a more varied diet that includes fresh vegetables and hay. A balanced diet is crucial for digestive health and overall well-being.

In contrast, regular exercise is vital as it prevents obesity and promotes mental stimulation; consistent climate control helps avoid stress and temperature-related illnesses; and providing clean water is essential for hydration and the proper functioning of bodily systems. Thus, feeding commercial pellets only is not sufficient and does not encompass the broader dietary needs of rabbits.
