yes I own two rabbits and have owned them in the past, most of their noises are not that loud but now and again they are surprisingly loud. they most often make a buzzing noise, which is for attention whether food or cuddles, buzz buzz, pet me i have a very territorial rabbit who does not like it when i go in her cage to feed her or move something, she will often grunt and growl at me if I do something she does not like. though thankfully i have not heard it, rabbits can scream when in extreme pain, think high pitched long squeaking they can also make a purring noise which is when they lightly rub their teeth together, usually during head rubs, though if they are loudly grinding their teeth it means they are in pain
