It's best not to eat grass indiscriminately. Rabbits are no better than wild rabbits. Rabbits raised at home now, whether pet rabbits or meat rabbits, are domestic and domesticated rabbits. Domestic rabbits should have no problem with the food they need. It's best not to eat weeds outside. However, the most common grass growing on the ground is occasionally eaten by other plants. If there is no confirmation or uncertainty, don't give it anything to eat.
