Pet rabbits can eat bananas, but they should not be fed too much and should be fed in small amounts. If fed too much, it will easily cause vomiting, diarrhea and other conditions in the rabbit. It is also best not to eat fruits for rabbits under three months old. Rabbits normally do not need to eat fruits, but if you want to feed them, you can occasionally feed them less. It is also best not to give peels and cores to rabbits because they contain toxins.
