Welcome Ivagrove, I'm quoting from Pamnock belowwho explains it well. I'm hoping that she doesn't always havesoft stool, it's just the cecotropes.
"Coprophagy", the eating of feces, is an important part of yourrabbit's health and is the manner in which rabbits "manufacture" andredigest complex B vitamins. These special feces that therabbit eats are called "cecotropes".
