Could eating a small amount of avocado pit kill your rabbit?

Yes, eating a small amount of avocado pit could potentially harm or kill your rabbit. Avocado contains a substance called persin, which is toxic to many animals, including rabbits. While the flesh of the avocado is less harmful, the pit poses a choking hazard and can lead to digestive blockages. It's best to avoid feeding any part of the avocado to rabbits.
