Is it possible for two rabbits to share one litter box?

It is generally not recommended to have two rabbits share one litter box. Rabbits are territorial animals and having multiple litter boxes can help reduce the risk of territorial disputes and accidents outside the litter box. Additionally, sharing a litter box can increase the risk of spreading bacteria and parasites between the rabbits. Having separate litter boxes will allow each rabbit to have their own space to use the bathroom, which will make it easier to monitor their litter habits and maintain a clean environment for both rabbits.
