Ask the vet - Rabbit
Is it OK for rabbits to eat anything they like?
Vet at FirstVet answers:
Rabbits can eat all sorts of things that they should not eat, even things that can be poisonous to them. In other words, it is important as a rabbit owner to prevent your pet from eating inappropriate things. This also means that you should not give your rabbit a large amount of for example oranges just because your rabbit seems to enjoy them a lot.
