Solutions to rabbit teeth grinding:

1. Feed rabbits some pellet feed and grass. The pellet feed is relatively hard and can grind teeth. Chewing grass can also help with teeth grinding.

2. Prepare a molar stick or molar stone for the rabbit. You can buy it and put it in the rabbit's nest to help the rabbit grind its teeth.

3. If a rabbit grinds its teeth, it is likely that it has some physical problems or is suffering from some diseases. You should take it to the hospital for examination.

Notes on raising rabbits:

1. Rabbits should be raised in a quiet environment. Rabbits are very timid and are easily affected by sounds.

2. When feeding a rabbit, make sure the food is balanced. Feed it not only some grass, but also some fresh vegetables and fruits.

3. Clean the rabbit's cage frequently and disinfect the items used by the rabbit regularly to ensure that the rabbit lives in a clean and hygienic environment.
