Someone I know told me that her rabbit growls. At first I was skeptical. The first thing I thought of was that it might have had respiratory problems and that it sounds like it's growling, because she uses cedar shavings.

But I went to her house, and, sure enough, when the girl stuck her hand in the cage, the rabbit made very loud growling/gurgling noises, and started screaming, like a dieing cat!

I've only had three rabbits in my life, but I've never seen this behaviour. My mom has had dozens of rabbits, and she's only had one that made a weird noise.

Is this normal? I have no idea what to think about this, it's so odd!
